Hibernation. 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 metabolic rate. It is most commonly used to pass through winter months – called overwintering.
e. A hibernaculum (plural form: hibernacula) (Latin, "tent for winter quarters") is a place in which an animal seeks refuge, such as a bear using a cave to overwinter. The word can be used to describe a variety of shelters used by many kinds of animals, including insects, toads, lizards, snakes, bats, rodents, and primates of various species.
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 ...
List of mammalian gestation durations. This is a collection of lists of mammal gestation period estimated by experts in their fields. The mammals included are only viviparous (marsupials and placentals) as some mammals, which are monotremes (including platypuses and echidnas) lay their eggs. A marsupial has a short gestation period, typically ...
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 ...
Bears normally stock up on food then hibernate in their dens during the coldest winter months. Bear hibernation is “strongly tied” to weather patterns and food availability, according to a ...
Tardigrades are usually about 0.5 mm (0.020 in) long when fully grown. [ 2 ] They are short and plump, with four pairs of legs, each ending in claws (usually four to eight) or suction disks. [ 2 ][ 15 ] Tardigrades are prevalent in mosses and lichens and feed on plant cells, algae, and small invertebrates.
Allactaginae. Cardiocraniinae. Dipodinae. Euchoreutinae – long-eared jerboa. Jerboas (/ dʒɜːrˈboʊə / ⓘ) are hopping desert rodents found throughout North Africa and Asia, [1] and are members of the family Dipodidae. They tend to live in hot deserts. [1] When chased, jerboas can run at up to 24 km/h (15 mph). [1]
