Torpor
state of decreased physiological activity in an animal
Torpor is a physiological state of the body. It occurs in some small warm-blooded animals when food is scarce.
Some animals have periods of torpor every day, including hummingbirds.[1][2] So do some small mammals, for example, rodent species (such as mice), and bats.[3] Many small marsupials also have daily periods of torpor.[4]
Torpor is a well controlled thermoregulatory process. It is not the result of switching off thermoregulation.[5]
