Sleep is a natural state of bodily rest observed throughout the animal kingdom. It is common to all mammals and birds, and is also seen in many reptiles, amphibians and fish. In humans, other mammals, and a substantial majority of other animals which have been studied � such as fish, birds, ants, and fruit-flies � regular sleep is essential for survival. However its purposes are only partly clear and are the subject of intense research.
