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 ...
Winter is finally here, and bears are getting ready to find a den to hibernate in over the next few months. In Wyoming's Yellowstone National Park, one bear was caught prepping for his long sleep ...
Northern bat hibernating in Norway Bats hibernating in a silver mine. Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. . Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metaboli
Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is known as hibernation if it occurs during winter or aestivation if it occurs during the summer.
Crepuscular, a classification of animals that are active primarily during twilight, making them similar to nocturnal animals. Diurnality, plant or animal behavior characterized by activity during the day and sleeping at night. Cathemeral, a classification of organisms with sporadic and random intervals of activity during the day or night.
This is a widely used strategy across all forms of hypometabolism. These physiological and biochemical concerns appear to be the core elements of hypometabolism throughout the animal kingdom. In other words, animals which aestivate appear to go through nearly the same physiological processes as animals that hibernate. [2]
This species is nocturnal, with a diet of insects, other small animals, fruits and flowers. [12] The fat-tailed lemur is the only known primate to hibernate for extended periods of time, up to seven months. It performs this torpor during the dry season to minimise the impacts of droughts. During the wet season, it gorges on food, accumulating a ...
