Torpor is a (usually short-term) state of decreased physiological activity in an animal, usually characterized by a reduced body temperature and rate of metabolism. Animals that go through torpor include birds (even tiny hummingbirds) - notably Cypselomorphae - and some small mammals such as bats. During the active part of their day, these animals maintain normal body temperature and activity levels, but their body temperature drops during a portion of the day (usually night) to conserve energy. Torpor is often used to help animals survive during periods of colder temperatures, since it allows the organism to save the amount of energy that would normally be used to maintain a high body temperature.
Torpor may extend for a longer period of time. Some animals such as groundhogs, chipmunks, ground squirrels and jumping mice enter this intensely deep state of hibernation for the duration of the winter. Lungfish switch to the torpor state if their pool dries out; tenrecs switch to the torpor state if food is scarce during the summer (in Madagascar). Black bears, although often thought of as hibernators, do not truly enter a state of torpor: While their body temperatures lower along with respiration and heartbeat, they do not decrease as significantly as most animals in a state of torpor. Still, there is much debate about this within the scientific community: Some feel that black bears are true hibernators that employ a more advanced form of hibernation.[How to reference and link to summary or text]
Other uses of the wordEdit
- Torpor is alternately used as a reference to any non-physiological state of inactivity. As an example, recently naturalists have learned that the female crocodile enters a deep torpor without aggression during their short egg laying period.
- Torpor is also used in vampire mythology, to describe the state that a vampire enters during the daylight hours. Thus, the vampire needs to have or find a safe and secluded spot that is shielded from sunlight. In some mythologies, the vampire also uses a guardian to protect him during the state of torpor. In some legends and fiction, torpor also refers to a period of indefinite hibernation entered by vampires who have gone long periods of time without feeding on blood, or those who've suffered mortal wounds but have not been destroyed. During this time the vampire appears to be completely dead, and he or she will not awaken until a drop of blood reaches them.
