A burrow is a hole or tunnel excavated into the ground by an animal to construct a space suitable for habitation or temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements, and can be found in nearly every biome and among various biological interactions .
Small or missing external ears, to reduce naturally occurring friction during burrowing. Short and stout limbs, since swiftness or speed of movement is less important than the strength to dig. Broad and stout forelimbs ( manus ), including long claws, designed to loosen the burrowing material for the hind feet to disperse in the back.
A hibernaculum (plural form: hibernacula) (Latin, "tent for winter quarters") is a place in which an animal seeks refuge, such as a bear using a cave to overwinter.The word can be used to describe a variety of shelters used by many kinds of animals, including insects, toads, lizards, snakes, bats, rodents, and primates of various species.
A so-called "cathedral" mound produced by a termite colony. Structures built by non-human animals, often called animal architecture, [1] are common in many species. Examples of animal structures include termite mounds, ant hills, wasp and beehives, burrow complexes, beaver dams, elaborate nests of birds, and webs of spiders.
Snakes use concertina locomotion for moving slowly in tunnels, here the snake alternates in bracing parts of its body on it surrounds. Finally the caenophidian snakes use the fast and unusual method of movement known as sidewinding on sand or loose soil. The snake cycles through throwing the front part of its body in the direction of motion and ...
All insects have antennae, however they may be greatly reduced in the larval forms. Amongst the non-insect classes of the Hexapoda, both Collembola and Diplura have antenna, but Protura do not. [9] Antennal fibrillae play an important role in Culex pipiens mating practices. The erection of these fibrillae is considered to be the first stage in ...
Other species of bee and some wasps dig holes in the ground or chew through wood. [7] In the species Megachile rotundata , for example, females construct tubular-shaped nests in rotting wood as well as small holes in the ground, creating, each cell made from circular disks cut from plant leaves using the bee's mandibles.

The ventral scales of sidewinding snakes are short and have small, microscopic holes in them to reduce friction, as opposed to the more spike-shaped ones of other snakes. These are more prominent in the African horned viper and sand vipers than the American sidewinder, theorised to do with the formers' environments being older by millions of years.
