Psammophile

A psammophile (/ˈ(p)sæmoʊfaɪl/ (P)SAM-oh-fyle)^[1] is a plant or animal that prefers or thrives in sandy areas. Plant psammophiles are also known as psammophytes. They thrive in places such as the Arabian Peninsula and the Sahara^[2] and also the dunes of coastal regions.

Because of the unique ecological selective pressures of sand, often times animals on opposite sides of the planet can convergently evolve similar features, a phenomenon sometimes referred to as ecomorphological convergence.^[3] The Crotalus cerastes native to American deserts and the Bitis peringueyi native to Namibian deserts have independently evolved sidewinding behavior to traverse across sand.^[4] In addition, the African jerboa and the American kangaroo rat have separately evolved a bipedal form with large hind legs that allow them to hop.
