Contents

Zebras share the genus Equus with horses and asses, the three groups being the only living members of the family Equine. Zebra stripes come in different patterns, unique to each individual.

Several theories have been proposed for the function of these stripes, with most evidence supporting them as a form of protection from biting flies. Zebras inhabit eastern and Southern Africa and can be found in a variety of habitats such as Savannah, grasslands, woodlands, shrub lands and mountainous areas.

They are preyed on mainly by lions and typically flee when threatened but also bite and kick. Zebra species differ in social behavior, with plains and mountain zebra living in stable harems consisting of an adult male or stallion, several adult females or mares, and their young or foals ; while Gravy's zebra live alone or in loosely associated herds.

In harem-holding species, adult females mate only with their harem stallion, while male Gravy's zebras establish territories which attract females and the species is promiscuous. Zebras communicate with various vocalizations, body postures and facial expressions.

A zebra's dazzling stripes make them among the most recognizable mammals. Historically, they have been highly sought after by exotic animal collectors, but unlike horses and donkeys, zebras have never been truly domesticated.

The quanta, a type of plains zebra, was driven to extinction in the 19th century. The English name zebra dates back to c. 1600, deriving from Italian, Spanish or Portuguese.

Its origins may lay in the Latin aquifers meaning “wild horse”; from Equus (“horse”) and ferns (“wild, untamed”). Aquifers appears to have entered into Portuguese as zero or zero, which was originally a name for a mysterious (possibly feral) equine in the wilds of the Iberian Peninsula during the Middle Ages.

In ancient times, the zebra was called hippotigris (“horse tiger”) by the Greeks and Romans. The word zebra was traditionally pronounced with a long initial vowel, but over the course of the 20th century the pronunciation with the short initial vowel became the norm in the UK and the Commonwealth.

The pronunciation with a long initial vowel remains standard in US English. A group of zebras is referred to as a herd, dazzle, or zeal.

Zebras are classified in the genus Equus (known as equines) along with horses and asses. The extinct quanta was originally classified as a distinct species.

Later genetic studies have placed it as the same species as the plains' zebra, either a subspecies or just the southernmost population. Equus originated in North America and direct paleogenomic sequencing of a 700,000-year-old middle Pleistocene horse metaphorical bone from Canada implies a date of 4.07 million years ago (MYA) for the most recent common ancestor of the equines within the range of 4.0 to 4.5 MYA.

Equus koobiforensis is an early zebra or equine basal to zebras found in the Hungary Formation, Ethiopia and the Olduvai Gorge, Tanzania, and dated to around 2.3 MYA.

E. oldowayensis is identified from remains in Olduvai Gorge dating to 1.8 MYA. It is suggested the species was closely related to the Gravy's zebra and may have been its ancestor.

Fossil skulls of E. Mauritanians from Algeria which date to around 1 MYA appears to show affinities with the plains' zebra. A 2017 mitochondrial DNA study placed the Eurasian E. voodoo and the subgenus Sussemionus lineage as closer to zebras than to asses.

Fertile hybrids have been reported in the wild between plains and Gravy's zebra. Hybridization has also been recorded between the plains and mountain zebra, though it is possible that these are infertile due to the difference in chromosome numbers between the two species.

Captive zebras have been bred with horses and donkeys ; these are known as Negroids. As with all wild equines, zebra have barrel-chested bodies with tufted tails, elongated faces and long necks with long, erect manes.

Their elongated, slender legs end in a single spade-shaped toe covered in a hard hoof. Their dentition is adapted for grazing ; they have large incisors that clip grass blades and highly crowned, ridged molars well suited for grinding.

The eyes of zebras are at the sides and far up the head, which allows them to see above the tall grass while grazing. Their moderately long, erect ears are movable and can locate the source of a sound.

Unlike horses, zebras and asses have chestnut callosities only on their front limbs. In contrast to other living equines, zebra forelimbs are longer than their back limbs.

Diagnostic traits of the zebra skull include: its relatively small size with a straight profile, more projected eye sockets, narrower rostrum, reduced post orbital bar, a V-shaped groove separating the metabolic and metastatic of the teeth and both halves of the enamel wall being rounded. Comparative illustration of extant zebra speciesZebras are easily recognized by their bold black-and-white striping patterns.

The belly and legs are white when striped, but the muzzle is dark and the skin underneath the coat is uniformly black. The general pattern is a dorsal line that extends from the forehead to the tail.

From there, the stripes stretch downward except on the rump, where they develop species-specific patterns, and near the nose where they curve toward the nostrils. The stripes on the legs, ears and tail are separate and horizontal.

Zebras also have complex patterns around the eyes and the lower jaw. Striping patterns are unique to an individual and heritable.

During embryonic development, the stripes appear at eight months, but the patterns may be determined at three to five weeks. For each species there is a point in embryonic development where the stripes are perpendicular to the dorsal and spaced 0.4 mm (0.016 in) apart.

Various mutations of the fur have been documented, from mostly white to mostly black. Albino zebras have been recorded in the forests of Mount Kenya, with the dark stripes being blonde.

The quanta had brown and white stripes on the head and neck, brown upper parts and a white belly, tail and legs. The cry psis hypothesis was proposed by Alfred Wallace in 1896 and suggests that the stripes allow the animal to blend in with its environment or break out its outline so predators can not perceive it as a single entity.

Zebra stripes may provide wonderful camouflage at nighttime, which is when lions and hyenas are actively hunting. In 1871, Charles Darwin remarked that “the zebra is conspicuously striped, and stripes on the open plains of South Africa cannot afford any protection”.

Zebras graze in open habitat and do not behave cryptically, being noisy, fast, and social. In addition, lions and hyenas do not appear to be able to discern stripes beyond a certain distance in daylight, thus making the stripes useless in disrupting the outline.

Stripes also do not appear to make zebras more difficult to find than uniformly colored animals of similar size, and predators may still be able to detect them by scent or hearing. The camouflaging stripes of woodland living ungulates like bongos and bush bucks are much less vivid and lack the sharp contrast with the background color.

A 2014 study could not find any correlations between striping patterns and woodland habitats. Closeup of mountain zebra stripes The confusion hypothesis states that the stripes confuse predators, be it by: making it harder to distinguish individuals in a group as well as determining the number of zebras in a group; making it difficult to determine an individual's outline when the group flees; reducing a predator's ability to follow a target during a chase; dazzling an assailant, so they have difficultly making contact; or making it difficult for a predator to judge the zebra's size, speed and trajectory via motion dazzle.

A 2014 computer study of zebra stripes found that the motion signals made by zebra stripes give out misleading information and can cause confusion via the wagon-wheel effect or barber pole illusion. The researchers concluded that this could be used against mammalian predators or biting flies.

The use of the stripes for confusing against mammalian predators has been questioned. The stripes of zebras could make group size look smaller, and thus more attractive to predators.

Zebras also tend to scatter when fleeing from attackers and thus the stripes could not obscure an individual's outline. Lions, in particular, appear to have no difficulty targeting and making contact with zebras when they get close and take them by ambush.

In addition, no correlations have been found between the amount of stripes and populations of mammal predators. The aposematic hypothesis suggests that the stripes serve as warning coloration as they are recognizable up close.

Biologist L. H. Matthews proposed in 1971 that the stripes on the side of the mouth signal to the animal's bite. As with known aposematic mammals, zebras have high predation pressures and make no attempt to hide.

However, they are frequently preyed on by lions, suggesting that stripes do not deter them but may work on smaller predators. In addition, zebras are not slow and sluggish like known aposematic mammals.

Regarding species and individual identification, zebras have limited range overlap with each other and horses can recognize each other using visual cues. In addition, no correlation has been found between striping and social behavior among equines.

The thermoregulation hypothesis suggests that stripes help to control a zebra's body temperature. In 1971, biologist H. A. Baldwin noted that black stripes absorbed heat while the white ones reflected it.

In 1990, zoologist Desmond Morris proposed that the stripes set up convection currents to cool the animal. A study from 2015 determined that environmental temperature is a strong predictor for zebra striping patterns.

Another study from 2019 also concluded that the stripes played a role in regulating heat. Air currents move faster over the heat-absorbing black hairs than the white ones.

At the junction of the stripes, the air swirls and cools down the animal. During the hottest times of the day, the raised hair may help transfer heat from the skin to the hair surface, while during the cooler early morning, the raised black hair can trap air to prevent heat loss.

Others have found no evidence that zebras have cooler bodies than other ungulates whose habitat they share, or that striping correlates with temperature. A 2018 experimental study which dressed water-filled metal barrels in horse, zebra and cattle hides found that zebra stripes have no effect on thermoregulation.

In addition, zebra hair is shorter or the same length as the mouth parts of horse flies. Car and colleagues (2019) reported this hypothesis as the “emerging consensus among biologists”.

It was found that flies were less likely to land on black-and-white striped surfaces than uniformly colored one's in 1930 by biologist R. Harris. A 2012 study concurred this and concluded that the stripes reflect contrasting light patterns rather than the uniform patterns these insects used to locate food and water.

A 2014 study found a correlation between the amount of striping and the presence of horse and tsetse flies. Among wild equines, zebras live in areas with the highest fly activity.

Other studies have found that zebras are rarely targeted by these insect species. A 2020 study found that zebra stripes do not dazzle or work like a barber pole against flies since checkered patterns also repel them.

White or light stripes painted on dark bodies have also been found to reduce fly irritations in both cattle and humans. Plains zebras have been recorded travelling 500 km (310 mi) between Namibia and Botswana, the longest land migration of mammals in Africa.

Plains zebras are more water-dependent and live in more music environments than other species. They seldom wander 10–12 km (6.2–7.5 mi) from a water source.

They regularly rub against trees, rocks, and other objects and roll around in dust for protection against flies and irritation. Zebras eat primarily grasses and edges but may also consume bark, leaves, buds, fruits, and roots if their favored foods are scarce.

Compared to ruminants, zebras have a simpler and less efficient digestive system. Zebras may spend 60–80% of their time feeding, depending on the availability and quality of vegetation.

The plains zebra is a pioneer grazer, mowing down the upper, less nutritious grass canopy and preparing the way for more specialized grazers, which depend on shorter and more nutritious grasses below. When threatened by lions, zebras flee, and when caught they are rarely effective in fighting off the big cats.

A lion has to surprise a zebra within the first six seconds of breaking cover. However, a 2018 study found that zebras do not escape lions by speed alone but by laterally turning, especially when the predator is close behind.

With smaller predators like hyenas and dogs, zebras may act more aggressively, especially in defense of their young. Plains and mountain zebras live in stable, closed family groups or harems consisting of one stallion, several mares, and their offspring.

These groups have their own home ranges, which overlap, and they tend to be nomadic. The stability of the group remains even when the family stallion dies or is displaced.

Among harem-holding species, this behavior has otherwise only been observed in primates such as the Nevada and the Madras baboon. Females of these species benefit as males give them more time for feeding, protection for their young, and protection from predators and harassment by outside males.

Among females in a harem, a linear dominance hierarchy exists based on the time at which they join the group. Harems travel in a consistent filing order with the high-ranking mares and their offspring leading the groups followed by the next-highest ranking mare and her offspring, and so on.

Young of both sexes leave their natal groups as they mature; females are usually herded by outside males to be included as permanent members of their harems. Group of Gravy's zebras grazing In the more arid-living Gravy's zebras, adults have more fluid associations and adult males establish large territories, marked by dung piles, and monopolize the females that enter them.

This species lives in habitats with sparser resources and standing water and grazing areas may be separated. The most dominant males establish territories near watering holes, where more sexually receptive females gather.

Staying in a territory offers a female protection from harassment by outside males, as well as access to a renewable resource. Mountain zebras quarrelling all species, excess males gather in bachelor groups.

These are typically young males that are not yet ready to establish a harem or territory. With the plains' zebra, the males in a bachelor group have strong bonds and have a linear dominance hierarchy.

Mountain zebra bachelor groups may also include young females that have recently left their natal group, as well as old males they have lost their harems. Bachelors prepare for their adult roles with play fights and greeting/challenge rituals, which make up most of their activities.

Fights between males usually occur over mates and involve biting and kicking. In plains zebra, stallions fight each other over recently matured mares to bring into their group and her family stallion will fight off other males trying to abduct her.

Agonistic behavior between male Gravy's zebras occurs at the border of their territories. Plains zebras mutually groomingWhen meeting for the first time, or after they have separated, individuals may greet each other by rubbing and sniffing their noses followed by rubbing their cheeks, moving their noses along their bodies and sniffing each other's genitals.

Plains and mountain zebras strengthen their social bonds with grooming. Members of a harem nip and scrape along the neck, withers, and back with their teeth and lips.

Grooming usually occurs between mothers and foals and between stallions and mares. Grooming shows social status and eases aggressive behavior.

Although Gravy's zebras do not perform social grooming, they do sometimes rub against another individual. The call of the Gravy's zebra has been described as “something like a hippo's grunt combined with a donkey's wheeze”, while the mountain zebra is relatively silent.

Zebras also communicate with visual displays, and the flexibility of their lips allows them to make complex facial expressions. Visual displays also incorporate the positions of the head, ears, and tail.

A zebra may signal an intention to kick by laying back its ears and sometimes lashing the tail. Flattened ears, bared teeth, and abrupt movement of the heads may be used as threatening gestures, particularly among stallions.

Captive Gravy's zebras matingAmong plains and mountain zebras, the adult females mate only with their harem stallion, while in Gravy's zebras, mating is more promiscuous and the males have larger testes for sperm competition. Estrus in female zebras lasts five to ten days; physical signs include frequent urination, flowing mucus, and swollen, reverted (inside out) labia.

In addition, females in estrous will stand with their hind legs spread and raise their tails when in the presence of a male. Males assess the female's reproductive state with a curled lip and bared teeth (freshmen response) and the female will solicit mating by backing in.

The length of gestation varies by species; it is roughly 11–13 months, and most mares come into estrus again within a few days after foaling, depending on conditions. Mountain zebra suckling a foalUsually, a single foal is born, which is capable of running within an hour of birth.

A newborn zebra will follow anything that moves, so new mothers prevent others from approaching their foals while imprinting their own striping pattern, scent and vocalization on them. Within a few weeks, foals attempt to graze, but may continue to nurse for eight to thirteen months.

Living in an arid environment, Gravy's zebras have longer nursing intervals and do not drink water until they are three months old. In plains and mountain zebras, foals are cared for mostly by their mothers, but if threatened by pack-hunting hyenas and dogs, the entire group works together to protect all the young.

The group forms a protective front with the foals in the center, and the stallion will rush at predators that come too close. In Gravy's zebras, mothers may gather into small groups and leave their young in kindergartens guarded by a territorial male while searching for water.

A stallion may look after a foal in his territory to ensure that the mother stays, though it may not be his. By contrast, plains zebra stallions are generally intolerant of foals that are not theirs and may practice infanticide and femicide via violence to the pregnant mare.

With their distinctive black-and-white stripes, zebras are among the most recognizable mammals. They have been associated with beauty and grace, with naturalist Thomas Pennant describing them in 1781 as “the most elegant of quadrupeds”.

Zebras have been popular in photography, with some wildlife photographers describing them as the most photogenic animal. Zebras have become staples in children's stories and wildlife-themed art, such as depictions of Noah's Ark.

They are known for being among the last animals to be featured in the dictionary and in children's alphabet books where they are often used to represent the letter 'Z'. Zebra stripes are also popularly used for body paintings, dress, furniture and architecture.

Zebras have been featured in African art and culture for millennia. They are depicted in rock art in Southern Africa dating from 28,000 to 20,000 years ago, though not as commonly as antelope species like eland.

How the zebra got its stripes has been the subject of folk tales, some of which involve it being scorched by fire. The Masai proverb “a man without culture is like a zebra without stripes” has become popular in Africa and beyond.

The San people associated zebra stripes with water, rain and lighting because of its dazzling pattern, and water spirits were conceived of having zebra stripes. For the Shone people, the zebra is a totem animal and is praised in a poem as an “iridescent and glittering creature”.

Its stripes have symbolized the joining of male and female and at the ruined city of Great Zimbabwe, zebra stripes decorate what is believed to be a Zomba, a premarital school meant to initiate girls into adulthood. For people of the African diaspora, the zebra represented the politics of race and identity, being both black and white.

In cultures outside its range, the zebra has been thought of as a more exotic alternative to the horse; the comic book character Sheena, Queen of the Jungle, is depicted riding a zebra and explorer OSA Johnson was photographed riding one. The film Racing Stripes features a captive zebra ostracized from the horses and ending up being ridden by a rebellious girl.

Zebras have been featured as characters in animated films like Thumb, The Lion King and the Madagascar films and television series such as You. Zebras have been popular subjects for paintings, particularly for abstract, modernist and surrealist artists.

Notable zebra art includes Christopher Wood's Zebra and Parachute, Lucian Freud's The Painter's Room and Quince on a Blue Table and the various paintings of Mary Redden and Sidney Nolan. Victor Leisurely depicted zebras as mere bands of black and white and joined together in a jigsaw puzzle fashion.

Carl Weight's Escape of the Zebra from the Zoo during an Air Raid was based on a real life incident of a zebra escaping during and consists of four panels like a comic book. In later times, captive zebras have been shipped around the world, often for diplomatic reasons.

In 1261, Sultan Barbara of Egypt established an embassy with Alfonso X of Castile and sent a zebra and other exotic animals as gifts. In 1417, a zebra was sent to the Dongle Emperor of China from Somalia as a gift for the Chinese people.

The fourth Mughal emperor Jahangir received a zebra via Ethiopia in 1620 and commissioned a painting of the animal, which was completed by USTA Manner. In the 1670s, Ethiopian EmperorYohannes I exported two zebras to the Dutch governor of Jakarta.

These animals would eventually be given by the Dutch to the Tokugawa Shogunate of Japan. When Queen Charlotte received a zebra as a wedding gift in 1762, the animal became a source of fascination for the people of Britain.

In 1882, Ethiopia sent a zebra to French president Jules Gravy, and the species it belonged to was named in his honor. It is possible that having evolved under pressure from the many large predators of Africa, including early humans, they became more aggressive, thus making domestication more difficult.

In Rome, zebras are recorded to have pulled chariots during gladiator games starting in the reign of Caracalla (198 to 217 AD). In the late 19th century, the zoologist Walter Rothschild trained some zebras to draw a carriage in England, which he drove to Buckingham Palace to demonstrate the tame character of zebras to the public.

In the early 20th century, German colonial officers in German East Africa tried to use zebras for both driving and riding, with limited success. Gravy's zebra populations are estimated at less than 2,000 mature individuals, but they are stable.

Mountain zebras number near 35,000 individuals and their population appears to be increasing. Plains zebra are estimated to number 150,000–250,000 with a decreasing population trend.

Human intervention has fragmented zebra ranges and populations. Zebras are threatened by hunting for their hide and meat, and habitat change from farming.

They also compete with livestock for food and water and fencing blocks their migration routes. Civil wars in some countries have also caused declines in zebra populations.

By the beginning of the 20th century, zebra skins were valued commodities and were typically used as rugs. In the 21st century, zebra hides still sell for $1,000 and $2,000, and they are taken by trophy hunters.

Zebra meat was mainly eaten by European colonizers; among African cultures only the San are known to eat it regularly. The quanta population was hunted by early Dutch settlers and later by Afrikaners to provide meat or for their skins.

The quanta was probably vulnerable to extinction due to its limited distribution, and it may have competed with domestic livestock for forage. The last captive quanta, a female in Amsterdam's Natural Artist Magistrate zoo, lived there from 9 May 1867 until it died on 12 August 1883.

The Cape mountain zebra, a subspecies of mountain zebra, was driven to near extinction by hunting and habitat loss with less than 50 individuals by the 1950s. Conservation efforts by the South African National Parks have since allowed the populations to grow to over 2,600 by the 2010s.

Zebras are members of the horse family (Equine) found only in Africa. This animal is best known for its stunning black and white patter nation and similar appearance to a domestic horse.

The Gravy’s zebra is the most at risk of extinction with only about 3,000 members of the species in the wild today. Much of their natural habitat is being converted to farmland and this also means that they must compete with livestock for food and water.

Conservation efforts Most conservation efforts focus on reducing illegal poaching and creating reserves (such as national parks) for these animals to live in safety. Zebra sperm and eggs are being frozen and stored to ensure the survival of this animal.

Once considered to be extinct in the wild, the stocky horse breed has recently been reintroduced to its native lands. Its population is now higher than it has been in generations, and captive breeding programs give hope that these incredible horses have a bright future.

There's no clear evidence to when the Przewalski's horse first emerged, but we do know they used to roam freely throughout Europe and Asia. Changes in the environment, hunting, and modern encroachment forced the herds of wild horses eastward into Asia.

The Przewalski's horse is equipped to survive in this harsh environment, but their population was completely wiped out by the 1960s. A German writer wrote about the horses as early as the 15th century, and scientific evidence shows the breed could be much older.

After Przewalski released his information on his namesake horse breed, things started going down hill for the already threatened subspecies. The population was already at risk due to loss of habitat, hunting, and a succession of unseasonably cold winters.

A German merchant named Carl Heisenberg made a career out of capturing the wild horses and selling them to zoos and circuses across Europe. During World War II, reports tell of how German soldiers slaughtered an entire herd of horses living in the Albania Nova Region of Ukraine.

With the Przewalski's horse on the brink of complete extinction, conservationists started a renewed effort to save the subspecies. The Zoological Society of London spearheaded an effort to work with Mongolian researchers and develop captive breeding programs.

Fact: A British zoo recently celebrated the birth of a rare Przewalksi's horse foal. There were an estimated 1,5000 horses by 1990, and breed programs around the globe were working together to reintroduce genetic diversity to the entire population.

Thanks to trading between multiple breeding programs, today's population is considered both sustainable and genetically diverse. And while captive breeding programs saved the subspecies, conservationists are also working to reintroduce the wild horses to their freedom.

For the first time in generations, the Przewalski's horse can be found living wild and free in Mongolia, Russia, and even the Chernobyl exclusion zone in Ukraine. This is a question many people who are intrigued about zoology and exotic animals may ask.

The answer to this question has long since been established by biologists based on careful research into these amazing creatures. To call zebras little more than African horses with black stripes might be a bit of an oversimplification.

Based on what we currently know about evolutionary biology, horses may have originated in the southeastern region of Europe. Zebras originated in the continent of Africa and fossil records prove this to be true.

The resultant hybrid, however, would not be able to reproduce due to differences in the chromosomes. This is why we have not seen these new creatures emerge even though horses were long since imported to Africa many, many centuries ago.

Over the centuries, Gravy’s zebra was a merciless hunt, in order to get a beautiful skin, which became a favorite decoration of the interior. More recently, it turned out that Gravy’s zebras eat especially tough kinds of herbs that can not be digested by cattle.

Currently, in Somalia and Ethiopia Gravy’s zebra is almost completely exterminated, only in Kenya it was possible to implement effective measures to preserve the species. Plains zebras have a solid population and seem to be surviving and thriving.

The Gravy's zebra lives in the grassy areas of Ethiopia and the northern regions of Kenya. This is an extremely rare species of zebra and one that is surely endangered.

The mountain zebra lives in South Africa, Angola, and Namibia. The expansion of human agriculture has also harmed the ability for these zebras to sustain themselves, leading to a major decline in their population.

Differentiation between the species can be made by their coats, in addition to their social behavior and geographic distribution. The spread of civilization has caused habitat loss, increased competition for resources, and poaching, all of which have contributed to the troubles of wild zebras in Africa.

Although Nike la does not have a project that directly protects zebras, many awareness campaigns address the plight of Africa’s endangered and threatened wildlife species as a whole. The Hartmann’s Mountain Zebra are sporadically distributed in four populations across Namibia and are also in three conservation areas in the Northern Cape, South Africa.

The Gravy’s Zebras are now mostly restricted to areas in the Horn of Africa, specifically Kenya and Ethiopia, and are regionally extinct in Somalia and Sudan. The species once had a much wider range throughout Kenya and Ethiopia, but suffered one of the most substantial reductions in distribution of any African mammal.

As equines, zebras have horse-like bodies with short manes, tufted tails, and a distinctive black and white striped coat. Each individual has its own unique pattern of stripes, which allows fellow zebras to identify one another and helps confuse predators by preventing them from singling out anyone in a herd.

They rely heavily on water holes and must reside near one, especially if feeding on coarse, dry grass. Zebras stay close to their family units, protecting each other if one gets injured, and grooming one another with their teeth as a show of affection.

In harems, zebras look out for one another by alerting the other members of predators through a loud bark or whinny. When faced with a predator, zebras often choose to act upon the “flight” instinct, using their long legs and great stamina to outrun danger.

Second, zebras are an important source of food for many of Africa’s carnivores, with as many as 30% killed by lions and hyenas. In return, the carnivores limit zebra populations and remove the sick individuals, which would otherwise overwhelm the region’s food resources and spread disease throughout the harem, respectively.

The Gravy’s Zebra population was once estimated to be more than 15,000 in the 1970s but dropped to less than 3,500 by the early 21st century, a 75% decline. They were, and still are, hunted for their meat and unique skins, and they are losing their habitat, including access to water and food, to the growing human population and its livestock.

Furthermore, climate change worsens the frequency and duration of droughts, which causes pose another threat to the species. The most significant threat to the Hartmann’s Mountain Zebras in Namibia is livestock production and farming activities that prevent access to food and water.

However, all three species have experienced declines in population over the past years, as all face the threat of habitat loss due to the spread of civilization throughout the African continent. This results in many creatures flocking to one water hole in an area, which increases the transmission of diseases amongst zebras.

Population management efforts also help the species survive the major threats they face today. However, Kenya has recently taken steps to develop a national conservation strategy for the zebra.

The species was listed as a ‘Game Animal’ under the Wildlife Conservation and Management Act No. An icon of the African plains and a necessity in any wildlife documentary, the zebra is actually in trouble.

George Edward Lodge / Wikimedia Commons / Public Domain We wouldn't think of peacocks as endangered, considering you can find them in any wildlife park, petting zoo, and even the occasional farm.

Though you may see a flock around that sugar-water feeder you set out, quite a few hummingbird species are actually listed as endangered by IUCN. Closely related to but genetically unique from its domestic cousins, this wild horse is endangered.

Currently, there are about 178 mature horses living in the wild with more individuals in captive breeding programs and zoos. A major threat to the species is a loss of genetic diversity and, as a result, disease.

Howler monkeys are so common to Central and South America that it's hard to think there is any risk for them. But with habitat loss and capture or predation by humans, there is indeed a problem for several species.

The Yucatán black howler monkey is endangered and is expected to decline by up to 60% over the next 30 years. Meanwhile, the Maranhão red-handed howler monkey is also endangered, with approximately 250 to 2,500 mature individuals remaining in the wild.

Most of the decrease in fruit bat population is due to hunting, habitat loss, and disturbances to roost sites. Rodents are usually a surprise for the Endangered Species List since they tend to be great at adapting and especially skilled at reproducing.

Thanks to agricultural development, urbanization, and a lot of rodenticide, California's San Joaquin antelope ground squirrel (also known as the Nelson’s antelope squirrel), with only 20% of its former range, has an unknown but decreasing population. Found in the salt marshes bordering San Francisco Bay, the salt-marsh harvest mouse is impacted by habitat loss as a result of residential and commercial development, dam and water management systems, and invasive plant species.

Populations of the sun parakeet, estimated to be between 1,000 and 2,500 individuals, have declined due to trapping for the cage-bird trade as well the diminishing quality of their habitat. There are as few as 2,500 mature individuals left and researchers estimate the species has experienced a population decline of at least 50% over the last three generations.

The two do not share a habitat, however, as the pygmy hippo is only found in Liberia, Ivory Coast, Sierra Leone, and the Guinea regions of West Africa. While the pygmy hippopotamus population in the wild is unknown, the total number of mature individuals is estimated to be between 2,000 and 2,500.

Deforestation is the greatest threat to the pygmy hippo, but this animal is also hunted for meat. Pinnies are geniuses in the marine world, but sadly their smarts can't keep them off the Endangered Species list.

The Seller sea lion, the fourth largest Winnipeg behind walruses and two types of elephant seals, has a global population of around 81,300 animals. The western Seller sea lion population has continued to decrease due to disease and killing by fishermen, while the Loughlin’s Seller sea lion population is trending upward.

As with zebras, no documentary about the African savanna is complete without a few gazelles being caught by lions or cheetahs. The spoke's gazelle (pictured above) from the Horn of Africa is considered possibly extinct in Ethiopia, while remaining populations in Somalia, thought to be in the tens of thousands, face severe pressure from hunting and habitat loss.

They are all living in Africa (no zebras on other continents except in zoos) and they belong to the “Equine family of the Equus genus”. All zebras that we find today have stripes all over the body.

It was very common in South Africa and it was often described as a horse and zebra hybrid. You cannot train and teach a zebra to be ridden like a horse.

We find a very different type of animal with the zebra when it comes to domestication. This all has to do with the herd mentality among horses which would don’t find to the same extent with zebras.

Among a group of horses, we will always have the leading alpha male which is the leader of the flock. They do move around in groups but that’s more because there are obvious benefits than because they follow the leader of the flock.

As we looked at above, the horse’s legs are longer and it also enables it to run quite a lot faster than the zebra. The seating area of the horse where you mount the saddle is also very different build on the zebra.

Zebras don’t have the wither which is where the neck of the horse begins. Some people believe that zebras are faster than horses, but they are wrong.

As you can see below horses are faster than zebras and there’s a good physical explanation for that. Zebras are typically around 5 feet (1.5 meters) from the shoulder to the hoof.

The horse, on the other hand, is more like 5.5 feet (1,68 meters) from the shoulder to the hoof. Horses have long beautiful manes that can be braided in many ways.

As you can see from the picture above, the mane of the zebra is standing up and looks much more like that of a Donkey. We all know that a horse will neigh and you can also hear this sound among a flock of zebras.

The zebra can also produce a barking-type sound that is more similar to that of a smaller dog. There is a tiny bump where the horse withers is but nothing to support the saddle or keep the rider in place.

The dip is also absent and that makes it very hard to ride the zebra even if they had the temper for it. We will look a lot more at why it’s almost impossible to domesticate and train a zebra in the next section.

They will both kick a fellow stallion if they are provoked They both have hoofs that are similar They sleep standing up. They are both herbivores and will eat primarily herbs, leaves, and grass in the wild.

Zebras and horses belong to the same family tree. That the main thing there is to say about similarities between zebras and horses.

Other than that, they have an obvious list of commonalities when you look at how they are built and how they move. They are obviously closely related, as we mentioned at the beginning of the article.

Zebras are closer related to horses than donkeys. They all belong to the Equus family tree and zebras are directly related to horses whereas donkeys are one branch farther away from horses than zebras are.

Most racehorses and draft horses are a bit bigger than zebras. Zebras are loners that don’t like to be cuddled or managed.

So it’s quite hard to tell whether they are intelligent enough to do much else than just living their life on the African Savannah. Remember, they are very aggressive and people have not managed to domesticate them in any way or to ride them.

The Equine family again belongs to the Perissodactyla order, that includes Tapirs and Rhinos as well. Many of the most popular horse breeds today were also once endangered, often not that long ago.

It is one of the few remaining horses that was specifically bred for regional farm work needs. The Suffolk region is filled with wetlands and marshes, so this breed was adapted to those conditions.

One of the oldest recognized endangered horse breeds hovers around the 1,000 marks as well in terms of population. They have a smooth gait, a sensitive personality, and generally have a dark brown or chestnut coat.

It’s more of a miniature horse than a pony, especially since the average height tends to be between 9-10 hands. Their strength allowed them to carry a knight clad in full armor out into battle with relative ease.

Although their numbers are estimated to be around the 2,000 mark, they are still used for heavy agricultural work, especially in the forestry industry. Often used in the mining industry, their numbers have continued to dwindle since World War II.

All other horses are considered to be feral, including Rubies and Mustangs, because of how the herds or mobs were originally formed. Although the current populations are born in the wild, the ancestry of the feral horse is one that includes domestication.

They would be completely extinct if a zoo hadn’t maintained a single stallion and a handful of mares to preserve it. You’ll find this horse in national parks, wildlife sanctuaries, and even in the Chernobyl Exclusion Zone.

In 1989, only three small herds existed for this breed, along with 100 horses owned by private families. Although an estimated 300 horses are currently registered and numbers are continuing to rise, this rare breed is still considered to be extremely endangered.

Native to South Carolina, this is another horse breed that is directly descended from Spanish colonists in the 1500s. To help protect the breed, DNA testing was conducted in 2006-2007, leading to a closed stud book to be created in 2010.

This horse tends to be thinner and lankier compared to other breeds as well, creating features that appear to be quite delicate. Originally developed in Turkmenistan to be used for transportation and agricultural work, this breed is hardy and athletic.

This horse breed was almost exclusively developed in the Black Forest region of Germany. After mechanization reduced the need for farms to have working horses, this breed dropped in popularity almost immediately.

There are now about 1,000 horses in this breed and its popularity continues to bring it back from the brink of extinction. They are gray, but appear to be nearly white, and when a herd gallops through the wetlands, it makes for quite a sight.

Watching them has become so popular, in fact, that tourism opportunities to take photographs has started to create a resource base that can help to preserve the breed. The breed originally developed in Argentina in the mid-1800s before being imported to the United States in 1962.

They are highly intelligent as a breed, often used as guide or service and support animals for those with physical or emotional disabilities. They are also one of the longest-lived horse breeds in the world today, with many living longer than 40 years.

Their presence is known to restore the balance of a local ecosystem because of their endurance in wetland systems. Endangered horse breeds can be saved when the right supports are put into place.
