Sleep can follow a physiological or behavioral definition. In the physiological sense, sleep is a state characterized by reversible unconsciousness, special brainwave patterns, sporadic eye movement, loss of muscle tone (possibly with some exceptions; see below regarding the sleep of birds and of aquatic mammals), and a compensatory increase following deprivation of the state, this last known ...
The event takes place at night to minimize predation. The rain on the big night keeps the salamanders skin from becoming dry. [1] Amphibians such as salamanders and frogs in a local area usually use the same overwintering area and the same breeding area, returning generation after generation to the area in which they were spawned.
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate.Torpor enables animals to survive periods of reduced food availability. [1]
Worms, fish, insects, reptiles and amphibians are all cold-blooded. Mammals and birds are warm-blooded. A snake was found in a Woodbridge garage in Bluffton on Monday night.
During the day, amphiumas hide in vegetation, and at night they become active hunters. Their prey includes frogs , snakes , fish , crustaceans , insects and even other amphiumas.

Amphisbaenia / æ m f ɪ s ˈ b iː n i ə / (called amphisbaenians or worm lizards) is a group of typically legless lizards, [2] comprising over 200 extant species. Amphisbaenians are characterized by their long bodies, the reduction or loss of the limbs, and rudimentary eyes.
The desire for, or occurrence of, more sleep during winter may have to do with how light fluctuates throughout the year, or with the behavioral and mental health changes that can result.
