The racers (Coluber), the burrowing sand skink (Scincus), and the batagurid turtle (Mauremys caspica) are elements of this fauna in North Africa.
Many gobies, such as the longjaw mudsucker (Gillichthys mirabilis) of the eastern Pacific, inhabit burrows in sand or mud, and some share burrows with other animals.
Crab plovers (Dromas ardeola) breed colonially in burrows in sand banks and fashion a nest chamber at the end of the narrow, three-to-five-foot tunnel.
They dig their own burrows in sand or loose soil.
This can allow ordnance to penetrate concrete and explode in an underground tunnel or bunker, or, alternately, to burrow into sand before exploding — reducing the blast wave, shrapnel and risk to people and property nearby.
The foot of a bivalve mollusk is a bulbous or tonguelike organ that is used for burrowing in sand or mud.
Found worldwide in shallow seas, cake urchins burrow in sand and feed on organic particles wafted to the mouth on water currents.
Most toads of the genus Bufo and many genera in the families Rhinophrynidae, Pelobatidae, Myobatrachidae, Leptodactylidae, Hylidae, Ranidae, and Microhylidae burrow in sand, soil, or mud.
Appropriate coordination of muscular action working against the hydrostatic skeleton can produce locomotion movements—such as burrowing in sand or stepping along a hard surface by billowing out one side of the base of the animal while the other side of the base contracts, forcing fluid into the relaxed, dilated portion.
To test this hypothesis artificial scratches, under controlled load conditions, were created on the ventral skin material (epidermis) of four snake species adapted to different habitats: Lampropeltis getula californiae (stony and sandy soil substrates), Epicrates cenchria cenchria (trees, soil and water), Morelia viridis (trees), and Gongylophis colubrinus (burrowing in sand).
