Jerboas that live in sandy desert environments develop hairs on the bottom of their feet that allow for better traction and grip so that they don't slip in the sand. [ 5 ] Like other bipedal animals, their foramen magnum —the hole at the base of the skull—is forward-shifted, which enhances two-legged locomotion. [ 6 ]
The fennec fox's large ears help keep it cool: when the blood vessels dilate, blood from the body cycles in and dissipates over the expanded surface area. [1]A xerocole (from Greek xēros / ˈ z ɪ r oʊ s / 'dry' and Latin col(ere) 'to inhabit'), [2] [3] [4] is a general term referring to any animal that is adapted to live in a desert.
The domesticated dromedary is generally found in the semi-arid to arid regions of the Old World, mainly in Africa and the Arabian Peninsula, and a significant feral population occurs in Australia. Products of the dromedary, including its meat and milk, support several North African tribes; it is also commonly used for riding and as a pack animal.
The Bactrian camel shares the genus Camelus with the dromedary (C. dromedarius) and the wild Bactrian camel (C. ferus).The Bactrian camel belongs to the family Camelidae. [1] [5] The ancient Greek philosopher Aristotle was the first European to describe the camels: in his 4th century BCE History of Animals, he identified the one-humped Arabian camel and the two-humped Bactrian camel.
The pelts, particularly from the calves, are sometimes used as a substitute for red fox pelts, because the texture is difficult to differentiate. Like their domestic descendant, the llama, the guanaco is double-coated with coarse guard hairs and a soft undercoat, the hairs of which are about 16–18 μm in diameter and comparable to cashmere .

Species vary in size from 40 to 70 cm (16 to 28 in) in length and have long powerful back legs, and ears up to 20 cm (8 in) in length. Although usually greyish-brown, some species turn white in the winter. They are solitary animals. Newborns are precocial (eyes and ears open, fully furred).
Giraffe gestation lasts 400–460 days, after which a single calf is normally born, although twins occur on rare occasions. [105] The mother gives birth standing up. The calf emerges head and front legs first, having broken through the fetal membranes , and falls to the ground, severing the umbilical cord . [ 17 ]
