This is really interesting. There is such a variation in the sleep habits of animals. Even related species are not always alike.

I am impressed by the animals that can sleep while flying or swimming. That is quite a feat. The brain is amazing. It is able to sleep under what ever conditions it experiences.  Yes it is about survival, but the giraffe is too cute.
