Question

The carnivorous mammals like a cat, lion, panther, etc., walk silently and swiftly this kind of locomotion is called
A.Digitigrade locomotion
B.Plantigrade locomotion
C.Unguligrade locomotion
D.None of the above

Answer 1

Hint:-
- The cat, lion, panther belongs to the same family Felidae.
- Carnivores are the organisms that feed on the other animals.
- They have a peculiar feature which helps them to catch their prey.
- This includes sharp nails, sharp canines, and tail which help them in body balancing.

Complete step-by-step solution:-
Felidae species have strong and flexible forelimbs which makes them run faster that helps in catching their prey.
Digitigrade locomotion- this is the type of locomotion only the toes and fingers will touch the ground but not the full sole of the feel. The species of Felidae shows this type of movement.
Plantigrade locomotion-this type of locomotion is shown by black bears where they have the presence of curved claws and they walk on the soles of their feet.It is also called sole walking.
Unguligrade locomotion – this type of locomotion is shown by a horse where only the hoof touches the ground. They walk only on their nails or digits.
 The carnivorous mammals like cat, lion, panther, etc., walk silently, and swiftly this kind of locomotion is called Digitigrade locomotion. The correct option is A.

Note:- The plantigrade type of foot is considered as the most primitive. The digitigrade and ungulate motion is said to have evolved later.
Digitigrade legs help the animals to run faster by taking spring-like jumps, their ankle gives a leverage for such a movement.
Although its disadvantage over plantigrade is that these animals lack weight- bearing ability.
