What does quadrupedal mean?
Quadrupedal means having four legs or moving on four limbs. It is used especially in biology, zoology, biomechanics, and evolutionary studies to describe animals whose usual movement depends on all four limbs, such as horses, dogs, cats, and many reptiles. The word can describe an animal, as in a quadrupedal mammal, or a form of movement, such as quadrupedal locomotion. Its meaning is more specific than simply four-legged: it usually implies that four limbs are the characteristic means of movement, rather than merely that an animal possesses four legs. Although quadruped can function as a noun meaning a four-legged animal, quadrupedal is normally an adjective. In general conversation, four-legged is often more natural, while quadrupedal is preferred when a precise zoological or anatomical description is needed.

Where does quadrupedal come from?
Quadrupedal comes from Latin quadrupedalis, meaning “of or like a four-footed animal.” That form is based on quadrupes, from quadri- (“four”) and pes or pedis (“foot”), the same broad Latin roots underlying English words such as pedal and pedestrian. The word entered English in the seventeenth century and was initially used chiefly in biological and anatomical contexts.
