Hibernation

It's that time of year again. I'm thinking of gaining a lot of weight and watching TV and sleeping for the next 6 months or so.
I have been thinking about what animals hibernate and checked it out, the list is pretty short. It's just the ground squirrel types (chipmunks, lemurs ect.), bears, bats, frogs, turtles, skunks, marmots, raccoons, earthworms (!) and snails. I would think that earthworms do not include C.elgans and I couldn't find anything on C.elegans hibernation. There are other forms of hibernation called torpor and estivation, so maybe these are present in more primitive organisms.
Apparently my pet bunny is not supposed to hibernate. If it is showing symptoms of hibernation, I read that I should take it to the vet.
What I ran into that was interesting, however, is that hibernation can be induced in a non-hibernating species using hydrogen sulphide. Apparently it a reversible and harmless process. And it suggests that humans may also possess this latent ability to hibernate. The applications of course are interesting and include getting astronauts to hibernate for those extra long journeys to Mars and for medical purposes.
