Most animals have amazing survivability and survive even in the toughest environments. When the weather is cold and food is scarce, these animals will hibernate into a deep sleep, so they can be used throughout the cold winter. Survive. Hibernation is indeed a smart survival mechanism. Below is a list of some hibernating animals.
10. Wood Frogs
If you see a frozen frog with ice crystals, no breath, no heartbeat, you may feel that it is dead. If it is a wood frog, it is actually hibernating. Wood frogs hibernate in logs or caves or under rocks or leaves. When they are hibernating, they stop breathing, the heart stops beating and ice crystals form in the blood.
9. Deer Mice
Deer mice have short lives and short torpor (light hibernation) periods. During cold weather, they torpor from morning to late afternoon bundled up with their buddies and then spend the night searching for food. Between their daily torpor and the shared heat from snuggling up together, deer mice are able to save valuable amounts of energy.
8. Common Poorwills
The Common Poorwills is the only bird that enters true hibernation, and a few other birds enter a mild hibernation. When the temperature becomes very cold, very hot or the food is scared, the Common Poorwills will go into hibernation, and if necessary, they can even hibernate when they hatch.
7. Ground Squirrels
Most types of ground squirrels are hibernating, and some are nine months in some years. They also hibernate lightly for other days during the rest of the year. Ground squirrels have a good hibernation environment, they excavate well-designed underground tunnels to provide storage for different foods.
In the cold winter, skunks become comfortable in their dens and hibernate with their intimate family. During their hibernation for a few months, they occasionally wake up and come out to eat.
When many people discovered that their hamster had died, the pet owners cried in panic, but they were in a slight hibernation. Once the hamsters are awakened by the rustling sound, they may wake up and feel scared. Hamsters torpor for a few days to a week at one time when the weather is cold. They will only torpor if there is plenty of food nearby so they can snack during brief waking bouts.
4. Prairie Dogs
Prairie dogs are not real dogs. They are actually rodents, but they do bark like dogs. They are also very good at weathering cold weather. The white-tailed prairie dogs hibernate in the winter, the black-tailed prairie dogs enter the mild hibernation for a few days, and in very cold weather conditions only hibernate in rare cases.
Bats are very interesting for a number of reasons. They are the only true flying mammals that use echolocation navigation, which has been around since the dinosaur era and they hibernate. Bats go into true hibernation, which means they are in such a deep sleep that they seem to be dead. During hibernation, the bat’s heart rate drops from 400 to 25 per minute, and its breathing slows so fast that it does not breathe for up to an hour.
According to the weather, the hedgehog will sleep anywhere from a few weeks to six months. During hibernation, their heart rate dropped by nearly 90%. If their body temperature drops too low, they will wake up briefly, let their waking heart rate warm their bodies, and then return to hibernation.
When people think of hibernating animals, bears are usually the first animals they think of. Ironically, bears are no real predators. They are more like hibernators. They can hibernate for six months without eating or drinking.
