Quadrupedalism

Quadrupedalism (pronunciation: /kwɒˈdruːpɪdəlɪzəm/) is a form of terrestrial locomotion where an organism moves by means of its four limbs or legs. Such animals are referred to as quadrupeds. The majority of quadrupeds are vertebrate animals, including mammals such as cattle and cats, and reptiles, like lizards.

Etymology

The term "quadrupedalism" is derived from the Latin words "quad" meaning four and "pes" meaning foot.
