Hibernation or Torpor?

When we talk about hibernation, what we really mean is to do what squirrels or bears or hamster bats do in winter when they don't have enough resources. Matteo Cherry is a professor at the University of Bologna where he studies hibernation. To put their body on standby, animals first have to find the right spot. You could think of hibernation as the natural state that may be the closer to death without actually going over.
