Arboreal organisms display many specializations for dealing with the mechanical challenges of moving through their habitats. [1] Arboreal animals frequently have elongated limbs that help them cross gaps, reach fruit or other resources, test the firmness of support ahead, and in some cases, to brachiate. [1]
Kivell and Schmitt note "Features found in the hominin fossil record that have traditionally been associated with a broad definition of knuckle-walking are more likely reflecting the habitual Pan-like use of extended wrist postures that are particularly advantageous in an arboreal environment.
Brachiation (from "brachium", Latin for "arm"), or arm swinging, is a form of arboreal locomotion in which primates swing from tree limb to tree limb using only their arms. During brachiation, the body is alternately supported under each forelimb.
The animals are vulnerable to bushfires due to their slow speed and the flammability of eucalypt trees. [23]: 26 The koala instinctively seeks refuge in the higher branches, where it is vulnerable to heat and fire. Bushfires divide the animal's habitat, which isolates them, decreases their numbers and creates genetic bottlenecks.
Arboreal mammalian folivores, such as sloths, koalas, and some species of monkeys and lemurs, tend to be large and climb cautiously. [4] Similarities in body shape and head- and tooth-structure between early hominoids and various families of arboreal folivores have been advanced as evidence that early hominoids were also folivorous.

European treefrog (Hyla arborea). A tree frog (or treefrog) is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state. [1] Several lineages of frogs among the Neobatrachia suborder have given rise to treefrogs, although they are not closely related to each other.
The presumed cursorial nature of theropod dinosaurs is an important part of the ground-up theory of the evolution of bird flight (also called the Cursorial theory), a theory that contrasts with the idea that birds' pre-flight ancestors were arboreal species and puts forth that the flight apparatus may have been adapted to improve hunting by ...
The northern olingo is a slender arboreal animal, with hind legs distinctly longer than the fore legs, and a long, bushy tail. The face is short and rounded, with relatively large eyes and short round ears. [6]
