You know how all kinds of animals stretch? Cats, dogs, people (ok, admittedly, not a wide sample)? What about whales? Do whales feel the need to work out the kinks? What about sharks or crocodiles?

Random question courtesy of APOD and that vertebra that popped and felt soooooo good.

I've heard of whales scratching their backs against rocks, etc. Maybe they stretch out the old spine while they're at it.
