Winter slows us humans down, and it also slows the animals down. Yet, unlike us, most of the animals that survive through the winter go into a state of hibernation. Do you know what it means to hibernate? Did you know there is controversy as to whether or not one fo the largest hibernators, the black bear should even be called a hibernator? It's true. In fact, some bear biologists call them super-hibernators to help distinguish what they're doing from other hibernators like squirrels and chipmunks. Want to know a bit more about what the difference really is? Check out this week's weekly Untamed Science video focussing on this hot winter ecology topic.
