The Equidae family is comprised of horses, donkeys, and zebras with only one existing family, Equus, which is made up of seven living species. The Equidae family most likely originated in North America, however, domestic zebras, horses, and donkeys now exist worldwide while wild horses and zebras exist only in Asia and Africa. All members of the Equidae family are herbivores, most of which graze on low quality vegetation to survive. In the wild Equidae, either live in close-knit herds led by a stallion or in fluid groups where the females float between males who possess resources. While only seven species currently exist, about 60 more species are known from fossils.

What are equines?

Equines are part of the mammal family, Equidae, that includes the modern horse, zebra, and ass. The equine family has 7 living species. Equines are odd-toed ungulates and have long, slender legs, long heads, long necks, manes, and long nails. All species of equines are herbivorous.

When did equines branch into horses and mules?

Mules are the result of breeding a female horse, and a male donkey. They were intentionally bred to bring out the best characteristics of horses and donkeys while eliminating any undesirable characteristics. Mules have been bred since 3,000 BCE.

What is the Coggins Test in equines?

The Coggins Test is a blood test in equines that is used to diagnose Equine Infectious Anemia (EIA). This disease causes equines to have fevers, anemia, edema, weight loss, and muscle wasting. Infected horses carry the disease for life, and there is no vaccine nor treatment for EIA.

Tarpan (Equus ferus ferus)
Dimensioned comparison drawing of the Tarpan compared to an average person

The Tarpan (Equus ferus ferus) also known as Eurasian wild horse was a subspecies of the wild horse that is now extinct. They had a gray coat with a pale underside and a stripe on their back. They also had small ears. The tarpan was native to Russia, but was known to roam all throughout Europe. In the mid-1800s farmers killed them as they were believed to be pests and the last tarpan died in 1909. There have been attempts to ‘breed back’ the tarpan which have resulted in the modern Tarpan that is now referred to as the Heck Horse.

Tarpans have a shoulder height between 48”–52” (122-132 cm), overall standing height of 54.3”-59.8” (138-152 cm), and body length of 70.9”-78.7” (180-200 cm). The weight of a Tarpan is between 661-882 lb (300-400 kg). Tarpans have a typical lifespan of 25-30 years.

Mongolian Wild Ass | Kulan (Equus hemionus hemionus)
Comparison illustration of the size of a Mongolian Wild Ass (Kulan) to a typical person

The Mongolian Wild Ass (Equus Heminous Heminous) also known as the Mongolian Khulan, is a subspecies of the Onager. It physically resembles a short-legged horse. They are native to the Mongolian and northern China region. The Mongolian Wild Ass lives in deserts, cold deserts, steppes, shrublands, and mountains. They are herbivorous and eat grasses, shrubs, and herbs. They obtain water by digging holes at dry river beds to access subsurface water. The Mongolian Wild Ass has a typical lifespan of 26 years in captivity and 14 years in the wild. They are not considered threatened to extinction.

Mongolian Wild Asses have a shoulder height between 39”–49” (99-124 cm), overall standing height of 41.3”-55.1” (105-140 cm), and body length of 55.1”-70.9” (140-180 cm). The weight of a Mongolian Wild Ass is between 441-573 lb (200-260 kg). Mongolian Wild Asses have a typical lifespan of 15-40 years.

Mule (Equus asinus × Equus caballus)
Scale illustration of an average Mule compared to a human

The Mule (Equus asinus x Equus caballus) is the offspring of a male donkey and a female horse. They are one of the most common working animals in the world and are the oldest known hybrid. They were likely first bred in what is now Turkey. Mules share a resemblance horses except for their long ears. Their skin is more resistant to the sun and rain than that of a horse. Mules typically eat grains, hay, and pasture. They have a lifespan of between 35 to 40 years. Mules are sterile due to the odd number of their chromosomes.

Mules have a shoulder height between 56”–68” (142-173 cm), overall standing height of 63”-78.7” (160-200 cm), and body length of 70.9”-86.6” (180-220 cm). The weight of a Mule is between 820-1,000 lb (372-454 kg). Mules have a typical lifespan of 30-40 years.

Quagga (Equus quagga quagga)
Scale illustration of an average Quagga compared to a human

The Quagga (Equus quagga quagga) was a subspecies of the zebra and is now extinct. They were recognized by their brown and white stripes that were mainly seen on the front of their bodies. They were native to South Africa until it became extinct in the late 1800s. They were believed to gather in herds of 30 to 50 individuals. They became extinct due European settlers killing them. They were grazers and fed on grasses, leaves, shrubs, and fruits. Scientists have bred an animal that looks similar to them through the help of DNA and selective breeding.

Quaggas have a shoulder height between 44”–48” (112-122 cm), overall standing height of 53.1”-57” (135-145 cm), and body length of 65”-70.9” (165-180 cm). The weight of a Quagga is between 551-661 lb (250-300 kg). Quaggas have a typical lifespan of 20-40 years.

Plains Zebra (Equus quagga)
Drawing comparing the dimensions of a zebra to a human

Zebra are a variation of the horse family known for their uniquely distinct coats of black-and-white stripes. Typically traveling in herds, zebra are found in many different habitats throughout Africa including grasslands, savannas, mountains, hills, and woodlands. Not unlike a fingerprint, the coat patterns on every individual zebra are different and are used as a form of camouflage that makes it difficult for predators to target a single zebra in a herd.

The average Zebra has an overall height of 51"-75" (130-191 cm), 42"-60" (107-152 cm), and body length of 64"-96" (163-244 cm). A typical Zebra weighs between 440-990 lb (200-450 kg) and has a lifespan of between 20-30 years.
