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.
This animal has a body length (including the head) of between 4 and 26 cm (1.6 to 10 in.), with an additional 7 – 30 cm (2.75 to 12 in.) of tail, which is always longer than the full body. Jerboa dental records reveal a slow increase in crown heights and that corresponds to a more open and dryer ecosystem.
Formerly, Dipodoidea contained only a single large family, Dipodidae, which contained jerboas, jumping mice, and birch mice as subfamilies. However, phylogenetic evidence found all three to be distinct families from one another, and thus they were split into three different families within Dipodoidea.
The harsh climate of most desert regions is a major obstacle in conducting research into these ecosystems. In the environments requiring special adaptations to survive, it is often difficult or even impossible for researchers to spend extended periods of time investigating the ecology of such regions.

Representative fauna in tropical deserts include the armadillo lizard, banded Gila monster, bobcat, cactus wren and cactus ferruginous pygmy owl. Moreover, some other animals in deserts including coyote, desert bighorn sheep, desert kangaroo rat, desert tortoise, javelina and Mojave rattlesnake, cougar. Overall, different tropical deserts have ...
Desert hedgehog from Eastern Saudi Arabia. The desert hedgehog is one of the smallest of hedgehogs. It is 5.5 to 11 inches (140 to 280 mm) long and weighs about 10 to 18 ounces (280 to 510 g). The quills (or spines to give their correct name) on its back can be banded with coloring similar to the four-toed hedgehog. It is usually identified by ...
One environment for meiofauna is between grains of damp sand (see Mystacocarida). In practice these are metazoan animals that can pass unharmed through a 0.5–1 mm mesh but will be retained by a 30–45 μm mesh, [5] but the exact dimensions will vary from researcher to researcher. Whether an organism passes through a 1 mm mesh also depends ...
