  • Do fishes sleep? This is not an easy question. It depends on what you mean by “sleep”. Most sleep researchers, being focused on mammals, recognise sleep when they see distinctive patterns of electrical activity of the brain. Fish, however, lack the complex brain structures from where these patterns originate. Another criterion to define sleep, used mainly in the field or in situations where electroencephalographs are not available, is prolonged eye closure. But fish do not have eyelids!
