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 ...
Various marine animals are capable of aerial locomotion, i.e., jumping out of the water and moving through air. Some possible reasons for this behavior are hunting, escaping from predators, and saving energy for swimming or breathing. Some of the jumping behaviors initiate gliding and taxiing in air, while some of them end up falling back to water.
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 ...
What is another name for a gnu? Answer: Wildebeest. When traveling in groups, this animal is referred to as a “mob.” Answer: Kangaroo. Among all the venomous snakes, this reptile is the longest.
In most animals, slow-wave sleep is characterized by high amplitude, low frequency EEG readings. This is also known as the desynchronized state of the brain, or deep sleep. In USWS, only one hemisphere exhibits the deep sleep EEG while the other hemisphere exhibits an EEG typical of wakefulness with a low amplitude and high frequency.
Albert II was a male rhesus macaque monkey who was the first primate and first mammal to travel to outer space. He flew from Holloman Air Force Base in New Mexico, United States, to an altitude of 83 miles (134 km) aboard a U.S. V-2 sounding rocket on June 14, 1949. Albert died upon landing after a parachute failure caused his capsule to strike ...
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.
Polar bears hunt primarily at the interface between ice, water, and air; they only rarely catch seals on land or in open water. [69] The polar bear's most common hunting method is still-hunting: [70] The bear locates a seal breathing hole using its sense of smell, and crouches nearby for a seal to appear. When the seal exhales, the bear smells ...
