"A shark will go catatonic on its back but you can't hold it there for long as it will suffocate if water doesn't pass through the gills " hypnosis of sharks by interferance with their electrical sensors is well known and dosnt cause them any ill effect the must swim to breath thing is a common misconception sharks will actually sit on the sea floor and bask most have muscles which pass water across the gills there are also ram breathers but they can go back to muscle breathing to take a rest its thought that some sharks take a nap the same as flamingos with half of the brain going to sleep while the other half is active |
