Sub-fossorial species weighing more than 80 grams (2.8 oz) have comparably lower basal rates [specify] than those weighing lower than 60 grams (2.1 oz). The average fossorial animal has a basal rate between 60% and 90%. Further observations conclude that larger burrowing animals, such as hedgehogs or armadillos, have lower thermal conductance ...
Horses can be considered cursorial grazers. A cursorial organism is one that is adapted specifically to run. An animal can be considered cursorial if it has the ability to run fast (e.g. cheetah) or if it can keep a constant speed for a long distance (high endurance). "Cursorial" is often used to categorize a certain locomotor mode, which is ...
An Alpine chough in flight at 3,900 m (12,800 ft). Organisms can live at high altitude, either on land, in water, or while flying.Decreased oxygen availability and decreased temperature make life at such altitudes challenging, though many species have been successfully adapted via considerable physiological changes.
In an example of convergent evolution, the southern marsupial mole resembles the Namib Desert golden mole (Eremitalpa granti namibensis) and other specialised fossorial animals in having a low and unstable body temperature, ranging between 15–30 °C (59–86 °F). It does not have an unusually low resting metabolic rate, and the metabolic ...
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 ]

Atractaspis aterrima, commonly known as the slender burrowing asp or mole viper, is a species of fossorial, venomous snake in the family Atractaspididae. [ 2 ] [ 3 ] [ 4 ] The specific epithet , aterrima , meaning "blackest", is the superlative form of the Latin adjective ater , meaning "black".
Cat senses are adaptations that allow cats to be highly efficient predators. Cats are good at detecting movement in low light, have an acute sense of hearing and smell, and their sense of touch is enhanced by long whiskers that protrude from their heads and bodies. These senses evolved to allow cats to hunt effectively at dawn and dusk.
