Where do shark sleep?
Most sharks do not sleep.If they stop swimming....they will die.They need water running through their gills to get oxygen.However.....some sharks, like the Nurse Shark, can stop swimming for a while & have a snooze.
Do sharks sleep, and if so, how do they do it?
Yes, sharks do sleep, but in a different way than humans. Sharks do not have eyelids, so they cannot close their eyes while sleeping. Instead, some sharks have to keep swimming to keep water flowing over their gills for oxygen. This is called "active rest." Other sharks can rest on the ocean floor or in a cave while still moving water over their gills to breathe.

no they r like all sharks if they sleep they die
How do sharks obtain oxygen while they sleep?
Sharks will usually sleep in a moving ocean current so that water flows through their gills constantly. plus they never really sleep as like you or I do their bodies are always in motion If their bodies are not in motion, they will sink.

Do sharks sleep?
Nurse sharks are the only species that appear to sleep, others remain in motion to force water over the gills so they can breathe.Human scientists do not know whether or not sharks sleep. See related link [1] below.Yes, sharks sleep. Some sleep have to move while sleeping because oxygen must continuously flow into their gills in order to obtain the oxygen they need to live. Others are able to stay still and force oxygen rich water to flow over their gills. Sharks also do not go into a deep sleep like humans do.Shark sleepSome say a shark never sleeps. It is unclear how sharks sleep. Some sharks can lie on the bottom while actively pumping water over their gills, but their eyes remain open and actively follow divers. When a shark is resting, they do not use their nares, but rather their spiracles. If a shark tried to use their nares while resting on the ocean floor, they would be sucking up sand rather than water. Many scientists believe this is one of the reasons sharks have spiracles. The spiny dogfish's spinal cord, rather than its brain, coordinates swimming, so it is possible for a spiny dogfish to continue to swim while sleeping.It is also possible that a shark can sleep in a manner similar to dolphins.[31] In this situation, one half of the brain sleeps at a time, thereby allowing the shark to be half conscious while sleeping.Sharks do not sleep, so if they stopped swimming to go sleep they would die. If all sharks slept They would be a endangered SpeciesMany researchers agree that sharks in sleep mode are almost in a trance-like state. Although several species of sharks can rest on ocean floors or reefs, a resting, swimming shark can be easily identified by its slow swimming mode. An alert shark is swimming much faster.
