Question

Perissodactyla consists of :
A) Even toed hoofed unguligrade mammals
B) Odd toed hoofed unguligrade mammals
C) Even toed non-hoofed digitigrade mammals
D) Odd toed hoofed digitigrade mammals

Answer 1

Perissodactyla includes three families that are the horses and their allies, the rhinoceroses and the tapirs.

Complete Answer:
a. Hoofed mammals or Ungulates square measure an outsized, diverse, and extremely undefeated cluster of terrestrial mammals classified into a series of orders and superorders. The Term "ungulate"originally noted phytophagous animals with hooves on the terminal digits (toes) of their legs. This foot structure is their distinctive morphological adaptation and process characteristic.

b. It is the group of herbivore mammals that contains one or three hoofed toes on each hind foot, that is they are odd-toed hoofed and includes horses, asses, zebras etc.

c. They bear weight equally on two of their five toes that is the third and fourth. various three toes are either gift, absent, vestigial, or informally in distinction, odd-toed ungulates bear weight on one (an odd number) of the five toes i.e, the third toe. Another distinction between the 2 is that order ungulates digest plant carbohydrate in one or further abdomen chambers instead of in their gut as a result of the odd-toed ungulates do.

d. Ungulates are digitigrades; they walk on their toes. The word ungulate is from the Latin word unguis, which suggests nail, claw, or hoof. Artiodactyls are even-toed (cloven-hooved) ungulates - a number of these include antelopes, camels, cows, deer, goats, pigs, and sheep.

Hence option b: Odd toed hoofed unguligrade is the correct answer.

Note: Perissodactyla is a group of herbivorous mammals characterized by the possession of either one or three hoofed toes on each hindfoot.
