The Funniest Sleeping Habits in the Animal Kingdom
Whether you are an early bird or a night owl, your sleeping habits as a person are still a lot more normal than those of some animals. When it comes to humans, our resting habits are very simple: we like to sleep at night when it’s dark and quiet. Some other animals, however, have very interesting sleeping habits.
Dolphins sleep with one eye open.
Not only do dolphins and other cetaceans sleep with one eye open, they keep one side of their brain awake as well. This happens because these animals live in water and need to keep moving so their bodies don’t cool down. So while one side of dolphins’ brains is sleeping, the other is awake keeping their bodies in movement.
