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.
Deserts occupy one-fifth of the Earth's land surface and occur in two belts: between 15° and 35° latitude in both the southern and northern hemispheres. [2] These bands are associated with the high solar intensities that all areas in the tropics receive, and with the dry air brought down by the descending arms of both the Hadley and Ferell ...
The Nama Karoo of Namibia has the world's richest desert fauna. [8] The Chihuahuan desert and Central Mexican matorral are the richest deserts in the Neotropics. [9] The Carnarvon xeric shrublands of Australia are a regional center for endemism. [1] The Sonoran and Baja deserts of Mexico are unusual desert communities dominated by giant ...

The world's largest non-polar deserts. Deserts occupy about one third of Earth's land surface. [6] Bottomlands may be salt-covered flats. Eolian processes are major factors in shaping desert landscapes. Polar deserts (also seen as "cold deserts") have similar features, except the main form of precipitation is snow rather than rain.
The skies are teeming, too: a southern desert shrike, a bird that impales its prey upon spiky branches, oil-black desert ravens and even a critically endangered Egyptian vulture. But most common ...
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 ...
