  • Artiodactyls are the most diverse, large, terrestrial mammals alive today.
  • Artiodactyls are paraxonic, that is, the plane of symmetry of each foot passes between the third and fourth digits.
  • Artiodactyls are divided into 3 suborders.

What characteristics is used to distinguish Artiodactyla ungulates from Perissodactyla ungulates?

These orders are distinguished primarily by the animals’ feet: the Artiodactyla are known as the even-toed ungulates in contrast to the Perissodactyla, or odd-toed ungulates. The name Artiodactyla comes from the Greek words artios, meaning entire or even numbered, and dactylos for finger or toe.

What animals did Artiodactyla resemble?

What is the difference between Artiodactyla and Perissodactyla mammals?

The hoof of a horse or cow is anatomically an enlarged toe. Artiodactyls such as deer, sheep, and goats walk on two toes; perissodactyls walk either on three toes (rhinos, tapirs, some extinct horses) or on one toe (living horses).

What are the characteristics of Equidae?

Equids are generally thick-skulled animals with stocky bodies. They are heavily haired, but the length of hair is variable. Most species have a mane on the neck and a lock of hair on the forepart of the head known as a forelock.

Which group is most closely related to artiodactyls?

In the “Within” tree, all artiodactyls, including hippos, are more closely related to each other than any are to the whales. In the “Without” tree, pigs are more closely related to hippos than are whales. The “Without” tree is more consistent with molecular evidence than is the “Within” tree.

What is the difference between even and odd-toed ungulates?

Odd-toed ungulates have an odd number of toes, while even-toed ungulates have an even number of toes (2 or 4). Odd-toed ungulates are able to digest plant matter in their intestines, while even-toed ungulates digest their meals in one or more stomach chambers.

Are zebras Perissodactyla?

perissodactyl, any member of the order Perissodactyla, a group of herbivorous mammals characterized by the possession of either one or three hoofed toes on each hindfoot. They include the horses, asses, and zebras, the tapirs, and the rhinoceroses.

What is Perissodactyla and Artiodactyla?

Perissodactyls are the ungulates that are odd-toed, as the number of toes is reduced. For e.g., from five down to one in horses and three, seen in rhinoceroses. The even-toed ungulates, Artiodactyla, have four toes as seen in hippopotamuses, camels, pigs or two as seen in cattle, sheep, deer, etc.

What animals belong to the perissodactyla family?

What species are in the Equidae family?

Equidae (sometimes known as the horse family) is the taxonomic family of horses and related animals, including the extant horses, donkeys, and zebras, and many other species known only from fossils. All extant species are in the genus Equus, which originated in North America.
