In counting legs, this list follows the conventions adopted in the relevant literature. For example, millipedes with gonopods are listed by numbers that exclude leg pairs that become gonopods. [2] [3] [4] Animals have been selected so that each number from 0 to 55 leg pairs has one example listed.
Quadrupedalism is a form of locomotion where animals have four legs that are used to bear weight and move around. An animal or machine that usually maintains a four-legged posture and moves using all four legs is said to be a quadruped (from Latin quattuor for "four", and pes , pedis for "foot").

The Etruscan shrew has a very fast heart beating rate, up to 1511 beats/min (25 beats/s) and a relatively large heart muscle mass, 1.2% of body weight. [3] The fur color on the back and sides is pale brown, but is light gray on the stomach. The fur becomes denser and thicker from fall through the winter. [8]
Centipedes have one pair of legs per body segment, with typically around 50 legs, but some species have over 200. The terrestrial animals with the most legs are the millipedes. They have two pairs of legs per body segment, with common species having between 80 and 400 legs overall – with the rare species Illacme plenipes having up to 750 legs ...
Tarsiers are small animals with enormous eyes; each eyeball is approximately 16 millimetres (0.63 in) in diameter and is as large as, or in some cases larger than, its entire brain. [ 16 ] [ 17 ] The unique cranial anatomy of the tarsier results from the need to balance their large eyes and heavy head so they are able to wait silently for ...

Peccaries have a complex stomach that contains four compartments. [34] Their fore stomach has fermentation carried out by microbes and has high levels of volatile fatty acid; it has been proposed that their complex fore-stomach is a means to slow digestive passage and increase digestive efficiency. [34] Hippopotamuses have three-chambered ...
