Habits of sleeping

After visiting tiger kingdom and seeing all the sleeping tigers, I realized a lot of animals sleep a lot! Dogs, horses, cats, snakes.. They eat and sleep, and run around when the burst of energy hits them. Otherwise they are out.

But then I got thinking about ants, do they ever sleep? Or frogs, or fish? How bout insects?? I know that most of them have a shorter life span... I like to think it is due to the fact they are running around with little sleep... So dear world, I think I will continue my sleeping habit of nap taking...
