Torpor

Torpor is a state of decreased physiological activity in an animal, usually by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability. A torpor bout can last a few hours to a few months, depending on the species and the time of year. The term "torpor" can refer to the daily torpor of birds and small mammals or to the hibernation of larger mammals.

Characteristics

Torpor is a survival tactic used by a wide range of different animals, especially those that live in cold climates. By reducing their metabolic rate and lowering their body temperature, animals can conserve energy during periods when food is scarce. This can be particularly important during the winter months, when many animals enter a state of hibernation.

Types of Torpor

There are two main types of torpor: daily torpor and hibernation.

Daily Torpor

Daily torpor, as the name suggests, is a short-term form of torpor that occurs on a daily basis. It is most commonly observed in small mammals and birds. These animals enter a state of torpor at a certain time each day, typically when food is most scarce.

Hibernation

Hibernation is a long-term form of torpor that can last for several months. It is most commonly observed in larger mammals, such as bears and bats. During hibernation, an animal's body temperature and metabolic rate can drop significantly, allowing them to conserve energy.
