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.
Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals. Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.
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 ...
Makara (Hindu mythology) – half terrestrial animal in the frontal part (stag, deer, or elephant) and half aquatic animal in the hind part (usually of a fish, a seal, or a snake, though sometimes a peacock or even a floral tail is depicted) Sea goat – Half goat, half fish; Selkie – Shapeshifting seal people
[236] [237] While population densities range from 0.5 to 3.2 animals per square kilometer (1.3 to 8.3 animals per square mile) in prairies and do not usually exceed 6 animals per square kilometer (15.5 animals per square mile) in upland hardwood forests, more than 20 raccoons per square kilometer (51.8 animals per square mile) can live in ...
Muskrats, like most rodents, are prolific breeders. Females can have two or three litters a year of six to eight young each. The babies are born small and hairless and weigh only about 22 g (340 gr). In southern environments, young muskrats mature in six months, while in colder northern environments, it takes about a year.
Digitigrade and unguligrade animals have relatively long carpals and tarsals, and the bones which correspond to the human ankle are thus set much higher in the limb than in a human. In a digitigrade animal, this effectively lengthens the foot, so much so that what are often thought of as a digitigrade animal's "hands" and "feet" correspond to ...
The subfamilies of nightjars have similar characteristics, including small feet, of little use for walking, and long, pointed wings. The common poorwill , Phalaenoptilus nuttallii , is unique as a bird that undergoes a form of hibernation, becoming torpid and with a much reduced body temperature for weeks or months, although other nightjars can ...
