Plantigrade Locomotion

What is plantigrade locomotion?

Plantigrade locomotion is the way some animals walk with their toes and metatarsals (heels) flat on the ground.

Terrestrial (land) mammals have three ways of walking:

(1) digitigrade (walking on their toes with their heels permanently raised),

(2) unguligrade (walking on the nail of their toes – the hoof – with the heel permanently raised), and 

(3) plantigrade (walking with their toes and heels on the ground).

The leg of a plantigrade mammal includes the bones of the upper leg, called the femur and humerus, and the bones of the lower leg, called the metatarsals and metacarpals.

Indian Crested Porcupine

The Indian Crested Porcupine (Hystrix indica) is a large rodent mammal in the Hystrididae family. 

The Indian Crested Porcupine is a stocky animal. It is black and covered with multiple layers of hair, called quills. The quills, made of keratin, are brown or black with black and white bands. Each quill has a muscle at its base, which enables it to rise and fall. The quills are not firmly attached, so they can easily come out. When these quills are vibrated, they produce a hiss-like rattle.

The Indian Crested Porcupine has broad feet with long claws that enable it to burrow into the ground. It has four toes on it front feet and five toes on its back feet. Its eyes and ears are small, and its nostrils are large. It has sharp teeth.
