I think they like turn half their brains off or something... Or is that dolphins? I'm sure they are simular.
Yeah I just looked it up, dolphins and whales are the ones that turn their brains half off, because they are conscious breathers they just cannot be fully unconscious incase they didn't wake up in time to breath. Fish (depending on what kind) Just rest or remain still propped up against a rock or maybe hidden somewhere, wedged into a log ect. Not sharks though, as they need to always be moving so the water passes through their gills. Lol I'm glad you asked this question. I always knew that the whales and dolphins turned half their brains off but I never really thought as to why. And now I know.
