Fossorial front leg of mole cricket, showing auditory and fossorial adaptations. Many fossorial and sub-fossorial mammals that live in temperate zones with partially frozen grounds tend to hibernate due to the seasonal lack of soft, succulent herbage and other sources of nutrition. [5]
Other adaptations to a fossorial lifestyle include a low resting metabolic rate of 0.946 ml O 2 /g/h, [3] and high conductance, a tolerance for low oxygen levels and high carbon dioxide levels, and a decreased water intake.
Mole crickets are cylindrical-bodied, fossorial insects about 3–5 cm (1.2–2.0 in) long as adults, with small eyes and shovel-like fore limbs highly developed for burrowing. They are present in many parts of the world and where they have arrived in new regions, may become agricultural pests.
The American spadefoot toads are of typical shape to most fossorial (or burrowing) frogs. They are round, with short legs and protruding eyes. As suggested by their name, these frogs have hard, keratinous protrusions present on their feet, which help them to dig. Like most fossorial frogs, they dig backwards into the ground. [1]

Most fossorial mammals, including the pocket gophers dig with their forepaws held directly below their body, but shrew-moles dig using lateral-strokes. [6] This method of lateral-stroke burrowing in shrew moles is an evolutionary adaptation due to the modification of the pectoral girdle and bones of the forelimbs. [6]
Gopherus is a genus of fossorial tortoises commonly referred to as gopher tortoises. The gopher tortoise is grouped with land tortoises that originated 60 million years ago, in North America. A genetic study has shown that their closest relatives are in the Asian genus Manouria. [1]
The species is highly fossorial, and feeds primarily on ants. These North American microhylids (Family: Microhylidae ) are distinguished from true toads (genus Bufo ), and other anurans by their moist, smooth skin, their lack of eardrums or tympana , their distinguishable squat body shape, and the unique fold of skin superior to their eyes.
