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.

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 ...
The common poorwill is the only bird known to go into torpor for extended periods (weeks to months). [2] This happens on the southern edge of its range in the United States, where it spends much of the winter inactive, concealed in piles of rocks. Such an extended period of torpor is close to a state of hibernation and is not known among other ...
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. Daily torpor, on the other hand, is not seasonally dependent and can be an important part of energy ...
Lizards were symbols of death and rebirth as they were believed to go into hibernation. [129] [130] [131] The ancient Greeks and Romans had numerous cultural depictions of salamanders. Aristotle and Theophrastus both describe the salamanders as a sign of rain. [132] Nicander stated that the salamander could be used to make poison.
Alaska Peninsula brown bears are among the largest types of brown bear in the world. They usually measure 8 ft (2.4 m) in length, usually have a shoulder height of about 4 to 4 1/2 ft or 1.22 to 1.37 meters (137 cm), and a hindfoot length of 11 in (28 cm). One study found that the average weight for a coastal male was around 408 kg (899 lb ...
The Utah prairie dog (Cynomys parvidens) is the smallest species of prairie dog endemic to the south-central steppes of the American state of Utah. The species is listed in the IUCN Red List of Threatened Species with a status of Endangered. Because of this, it is a protected species; the prairie dog faces various threats - the most dangerous ...
