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]
Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol ...
Six extant mustelid genera left-to-right, top-to-bottom: Martes, Meles, Lutra, Gulo, Mustela, and Mellivora Mustelidae is a family of mammals in the order Carnivora, which includes weasels, badgers, otters, ferrets, martens, minks, and wolverines, and many other extant and extinct genera.
Sloths are solitary animals that rarely interact with one another except during breeding season, [39] though female sloths do sometimes congregate, more so than do males. [40] Sloths descend about once every eight days to defecate on the ground. The reason and mechanism behind this behavior have long been debated among scientists.
Cebid monkeys are arboreal animals that only rarely travel on the ground. They are generally small monkeys, ranging in size up to that of the brown capuchin, with a body length of 33 to 56 cm, and a weight of 2.5 to 3.9 kilograms. They are somewhat variable in form and coloration, but all have the wide, flat, noses typical of New World monkeys.
Nine families of largely arboreal birds make up the order Piciformes / ˈ p ɪ s ɪ f ɔːr m iː z /, the best-known of them being the Picidae, which includes the woodpeckers and close relatives. The Piciformes contain about 71 living genera with a little over 450 species , of which the Picidae make up about half.
Overall, woodpeckers are arboreal birds of wooded habitats. They reach their greatest diversity in tropical rainforests, but occur in almost all suitable habitats, including woodlands, savannahs, scrublands, and bamboo forests. Even grasslands and deserts have been colonised by various species.
The claws on the front feet are larger than those on the back and may be a hindrance when climbing trees; black bears are the most arboreal of the bears, and have the shortest claws. Pandas are unique in having a bony extension on the wrist of the front feet which acts as a thumb, and is used for gripping bamboo shoots as the animals feed. [47]
