Plantigrade

Plantigrade is a form of locomotion in which the entire sole of the foot touches the ground during walking. This is in contrast to digitigrade locomotion, where only the toes touch the ground, and unguligrade locomotion, where only the tips of the toes touch the ground.

Characteristics

Plantigrade locomotion is characterized by the animal placing the entire sole of its foot on the ground with each step. This form of locomotion is less efficient than digitigrade or unguligrade locomotion in terms of speed, but it provides greater stability and strength.

Animals with Plantigrade Locomotion

Many mammals use plantigrade locomotion, including humans, bears, rodents, and rabbits. Some reptiles, such as lizards and crocodiles, also use plantigrade locomotion.

Advantages and Disadvantages

The main advantage of plantigrade locomotion is the increased stability it provides. This is particularly useful for animals that need to stand or walk on two legs, such as humans and bears. However, plantigrade locomotion is less efficient than other forms of locomotion in terms of speed and energy use.
