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 ...
Fossorial adaptations include small eyes, short, naked ears, and large fore feet with heavy claws. Zygomatic arches are widely flared, providing ample room for muscle attachment, [ 5 ] although, unlike other pocket gophers, this species does not use the curved incisors to assist the feet in digging.

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 ...
Semi-fossorial and aquatic musteloid species tend to have short and robust forelimb long bones to deal with the strain from digging and swimming. [5] In the order Carnivora, felids, which usually ambush and grapple with their prey, have shorter and more robust limbs. Their forelimbs are used for both short sprints and grappling, which means ...
Marsupial moles, the Notoryctidae / n oʊ t ə ˈ r ɪ k t ɪ d iː / family, are two species of highly specialized marsupial mammals that are found in the Australian interior. [2] They are small burrowing marsupials that anatomically converge on fossorial placental mammals, such as extant golden moles (Chrysochloridae) and extinct epoicotheres ().
In comparison to true moles, the fifth digit is absent and the first and fourth digits are vestigial. The adaptations of the hind feet are less dramatic: They retain all five toes and are webbed as an adaptation to efficient backward shoveling of soil loosened by the front claws. [4] At one time, the Chrysochloridae were regarded as primitive.
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.
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.
