The primary physiological and biochemical concerns for an aestivating animal are to conserve energy, retain water in the body, ration the use of stored energy, handle the nitrogenous end products, and stabilize bodily organs, cells, and macromolecules. This can be quite a task as hot temperatures and arid conditions may last for months, in some ...
While some aquatic animals move by "walking" along the ocean floor or burrowing, the predominant mode of fish locomotion is swimming, achieved by exerting force on the surrounding water which, by Newton's 3rd law, results in a reactive force that propels the animal forward.
Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
A common assumption is that Albatrosses must be able to sleep in flight, although no direct evidence has ever been obtained. [23] This efficient long-distance travelling underlies the albatross's success as a long-distance forager, covering great distances and expending little energy looking for patchily distributed food sources.
