Detailed explanation-1: -What is Hibernation? Hibernation is when an animal slows its heart rate to save energy and survive the winter without eating much. Some animals just slow down and move less frequently during hibernation, but others go into a deep sleep and don’t wake up till spring.

Detailed explanation-2: -Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months.

Detailed explanation-3: -Hibernation or “winter sleep” is the state of inactivity or low metabolic process animals perform during winter. Aestivation or “summer sleep”, on the other hand, is the low metabolic process by the animals during summer.

Detailed explanation-4: -Brumation is known as the hibernation for cold-blooded animals. Ectotherms rely on their environment to regulate their body temperature. Cold temperatures cause reptiles and amphibians to hide underground, in rock crevices and in burrows to stay warm and safe.

Detailed explanation-5: -Some animals make dens specifically for hibernating, called “hibernaculum.” These dens are hidden, insulated, and enclosed, and often contain “just in case” food stores. Other animals simply move into secluded spaces or take other animal’s dens.
