This strategy supports one-to-many associations provided that they are bidirectional. This list of animals that hibernate isn't an all-inclusive list; there are many more animals that hibernate or topor. But, we have highlighted some of.
They dig elaborate underground tunnels with different rooms for food storage, sleep and elimination yes, they have bathrooms. Ground squirrels go into hibernation as a response to a change in their blood. Scientists have been able to get an active ground squirrel to go into hibernation by injecting it with blood from a hibernating squirrel. Skunks During the cold winter months, skunks get comfy in their dens and torpor light hibernation in the company of their close family.
During their few month torpor, they occasionally wake up and come out to scrounge up something to eat.
- List of Animals That Hibernate
Hamsters Many a loving pet owner have cried out in dismay when they found their hamsters dead, only to learn they were actually in torpor a light hibernation. Once those hamsters were rustled about, they probably awoke pretty grouchy and scared. Hamsters hate being awoken from this state. In addition, the sudden disturbance can cause a heart attack, literally scaring them to death.
Why do bears hibernate?
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.
Prairie Dogs Prairie dogs aren't really dogs; they're actually rodents, but they do bark kind of like dogs. They also are really good at surviving cold weather.Developing one-to-many Uni-Directional Association Application in Hibernate using JPA Annotations
Depending on the species of prairie dog and the area it lives in, it either hibernates or goes into torpor. White-tailed prairie dogs hibernate through the winter.
10 Animals That Hibernate
Black-tailed prairie dogs go into torpor for a few days at a time, and only hibernate on rare occasions during extreme cold weather conditions.
Bats Bats are interesting for so many reasons.
They're the only true flying mammals, they navigate using echolocation, have been around since the dinosaur days and they hibernate. Many researchers thought that their deep sleep was not comparable with true, deep hibernation, but recent research has refuted this theory in captive black bears.
A good example of the differences between these two types of hibernation can be seen in prairie dogs: The hibernation of this lemur is strongly dependent on the thermal behaviour of its tree hole: It is now understood that the vast majority of bird species typically do not hibernate, instead utilizing torpor.
One known exception is the common poorwill Phalaenoptilus nuttalliifor which hibernation was first documented by Edmund Jaeger. It was once thought that basking sharks settled to the floor of the North Sea and became dormant, but research by Dr.
David Sims in dispelled this hypothesis,  showing that the sharks actively traveled huge distances throughout the seasons, tracking the areas with the highest quantity of plankton. Such dramatic changes can be taxing on their bodies, but the alternative, amid a starving winter, is almost certain death. So, come fall, the animals go into a controlled, coma-like state.
A black bear den. They do this even when they're well-insulated from the cold inside cozy, room-temperature conditions.
Something just triggers it. An appreciation of Holly, the fat bear mom who adopted and raised an abandoned cub Even though the scientific community was once largely on the fence about whether bears are true hibernators — because they can't dramatically drop their core temperature to freezing or below freezing temperatures — their torpid state was always considered an extraordinary feat, especially for so large an animal.
In order to make it happen, they must pack on excessive amounts of fat, especially for the long, dark subarctic winter inside Katmai National Park. Nowadays, however, many scientists do consider bears true hibernators.
And the females give birth and lactate during all of that. In black bears, Kelly regularly observes November hibernation heart rates of 50 beats per minute. But by January these rates plummet to less than half that.
Some have even fallen to around 10 beats per minute.
