Hi friends, can you tell me which is the only animal that doesn't sleep?

Answer 1

Sleep is the state of natural rest observed in most mammals, birds, fish, as well as invertebrates such as the fruitfly Drosophila. It is characterized by a reduction in voluntary body movement, decreased reaction to external stimuli, an increased rate of anabolism (the synthesis of cell structures), and a decreased rate of catabolism (the breakdown of cell structures). In humans, mammals and many other animals which have been studied, such as fish, birds, mice and fruitflies, regular sleep is necessary for survival. The capability for arousal from sleep is a protective mechanism and also necessary for health and survival. Sleep does not, as popularly believed, represent a state of unconsciousness
