There are 16 species of large mammals in this order in three families. The species in this order have an odd number of toes on their feet. In fact, they are sometimes called odd-toed ungulates.

What is the Perissodactyla order?

Therapsid
Odd-toed ungulates/Order

What are the characteristics of the order Perissodactyla?

The unifying characteristic of Perissodactyla is their single toe (or three toes together) bearing the weight of the animal, with the axis of each limb passing through the enlarged third digit. Tapirs have four digits on the forefeet and three digits on the hind feet, whereas rhinos have three digits on all feet.

Where are Perissodactyla found?

Their decline accelerated during the Oligocene and coincided with the rise of another group of large herbivorous and cursorial mammals, the artiodactyls. Modern perissodactyls are native to Africa, south and central Asia, southern North America, and northern South America. Most species are herbivorous.

Are humans Perissodactyla?

The order Perissodactyla, the group of odd-toed ungulates, includes three extant families: Equidae, Tapiridae, and Rhinocerotidae. Here we report the first genome-wide comparative chromosome maps of African rhinoceroses, four tapir species, four equine species, and humans.

What are Perissodactyla closely related to?

The order Perissodactyla includes three families: the horses and their allies (Equidae, the only family in the suborder Hippomorpha), the rhinoceroses (Rhinocerotidae), and the tapirs (Tapiridae). The last two families are closely related and are grouped together as the Ceratomorpha.

How many species in the family Perissodactyla are there?

Traditionally, there are three families within the order Perissodactyla: the Tapiridae (tapirs), the Rhinocerotidae (rhinoceroses), and Equidae (asses, horses, and zebras). These three families include six genera and 16 species.

Are there any perissodactyls left in the world?

Today there are far fewer species of perissodactyls than artiodactyls, and most of the species still living are endangered, especially the rhinoceroses, the tapirs, and two of the three species of zebras.

What kind of head does a Perissodactyla have?

The Perissodactyla Order have elongated heads with eyes on the sides of their face and nostrils near the other end of the head. They have muscular mouths with surfaced teeth to easily take in and chew vegetation. However, there are many differences among the three families in terms of head structure aside from these basic components.

How did the Perissodactyla ungulates get their name?

Perissodactylahorses, rhinoceroses, and tapirs. The name Perissodactyla means “odd-toed.”. This group of ungulates includes horses, tapirs, and rhinos. The name of their order derives from the fact that their middle toe is larger than the others, and the plane of symmetry of the foot passes through it, a condition called mesaxonic.
