Arboreal species have behaviors specialized for moving in their habitats, most prominently in terms of posture and gait. Specifically, arboreal mammals take longer steps, extend their limbs further forwards and backwards during a step, adopt a more 'crouched' posture to lower their center of mass, and use a diagonal sequence gait.

Non-crocodilian reptiles have 3-chambered hearts, which are less efficient because they let the two flows mix and thus send some de-oxygenated blood out to the body instead of to the lungs. Modern crocodilians' hearts are 4-chambered, but are smaller relative to body size and run at lower pressure than those of modern birds and mammals.
Sloths are a Neotropical group of xenarthran mammals constituting the suborder Folivora, including the extant arboreal tree sloths and extinct terrestrial ground sloths. Noted for their slowness of movement, tree sloths spend most of their lives hanging upside down in the trees of the tropical rainforests of South America and Central America.
Arboreal pangolins live in hollow trees, whereas the ground-dwelling species dig tunnels to a depth of 3.5 m (11 ft). [32] Some pangolins walk with their front claws bent under the foot pad, although they use the entire foot pad on their rear limbs. Furthermore, some exhibit a bipedal stance for some behavior, and may walk a few steps bipedally ...
Ring-tailed lemurs (Lemur catta), can be arboreal or terrestrial. While terrestrial, they move quadrupedally 70% of the time, bipedally 18% of the time, and by leaping the remaining 12% of the time. This is more bipedal locomotion than any other species in their genus. [18] While bipedal, they can locomote by hopping or walking. [18]
Many birds, mammals, and reptiles also practice social nesting or denning during cold weather and thus obtain the benefit of their partners’ body heat. Texas kangaroo rat burrow seen in a ...
The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the class Reptilia (/ r ɛ p ˈ t ɪ l i ə / rep-TIL-ee-ə), which
The prehensile-tail of a mantled howler monkey. A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. [1] Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees.
