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 – the so-called overwintering .
Aestivation ( Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1]
Dormancy is a period in an organism 's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy. Dormancy tends to be closely associated with environmental conditions. Organisms can synchronize entry to a dormant phase ...
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 ...
Marmot. Marmots are large ground squirrels in the genus Marmota, with 15 species living in Asia, Europe, and North America. These herbivores are active during the summer, when they can often be found in groups, but are not seen during the winter, when they hibernate underground. They are the heaviest members of the squirrel family.
The gang begins to wonder about animal lifespans and if any animals can live for 100 years or more, so they decide to travel the world in search of the longest-lived creatures. But someone else is also looking for the world's oldest animals-Zach Varmitech, who wants to discover the secrets to long life so that he can live forever.
Bears are carnivoran mammals of the family Ursidae ( / ˈɜːrsɪdiː, - daɪ / ). They are classified as caniforms, or doglike carnivorans. Although only eight species of bears are extant, they are widespread, appearing in a wide variety of habitats throughout most of the Northern Hemisphere and partially in the Southern Hemisphere.
As of late 2007, the species was the only mammal listed on the Connecticut endangered species list, [7] and it was the first mammal ever put on the list. [6] The greatest threat facing least shrews in the state is land development along the coast, which limits the land available for the species and isolates breeding populations.
