What is the difference between false hibernation and true hibernation?

I've been up and down google.com and i haven't found a feasible answer.





I know that hedgehogs undergo ';true hibernations'; while grizzlys undergo ';false hibernation';





btw, what category should this have gone under? pets? lolWhat is the difference between false hibernation and true hibernation?
Ok...I know about two different states...torpor and hibernation. Torpor is a state of inactivity that endotherms enter to conserve energy. Body temperature is lowered and metabolism is reduced. Many terrestrial birds undergo daily torpor. Now, hibernation...or winter dormancy, is a period of deep torpor that is considered long-term, lasting weeks or months and is devoid of rapid-eye movement. You are right that only small mammals enter this state of ';true hibernation.'; This is most commonly experienced by rodents, insects, and bats. It allows them to survive on energy reserves when food is scarce or non-existent. Grizzly bears, being considered a lare mammal, cannot truely hibernate. They simply enter a state of ';winter sleep'; in which body temperature only drops a few degrees. Bears are able so store sufficient energy reserves to enter this winter sleep without dramatically reducing body temperature, so they are not true hibernators.What is the difference between false hibernation and true hibernation?
never heard of false hibernation..... I heard of bears coming out of hibernation early.....
