Hibernation is a state of minimal activity and metabolic depression to survive cold winters.
Understanding Hibernation
Species like the Himalayan brown bear hibernate to escape the harsh Indian winter climate.
Brown Bears
While some squirrels may stay active throughout the winter, others do enter a state of torpor, similar to hibernation. Their body temperature drops, and they conserve energy by staying in their nests.
Squirrels
Pet hamsters may not hibernate in captivity, but their wild counterparts do enter a state of torpor during the winter. This helps them conserve energy when food is scarce.
Some frog species, such as wood frogs, bury themselves in the mud at the bottom of ponds and lakes to hibernate. Their bodies produce a special antifreeze that prevents them from freezing solid.
Frog
Many snakes hibernate in dens or rock crevices, where they coil up together for warmth. They may not eat at all during hibernation, relying on their stored body fat for energy.
Snakes
Both aquatic and terrestrial turtles can hibernate, burying themselves in mud or under leaves. Their heart rate and breathing slow down significantly, and they may even go without oxygen for several months.
