Do shark babies stay with mom?

Do sharks sleep?
While some species of sharks do need to swim constantly, this is not true for all sharks. Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.
Do sharks drink water?
There’s essentially as much urea and other chemicals in water inside a shark as there is salt in seawater. So the shark stays in balance with the saltwater outside its body and water doesn’t constantly flow out. Instead of drinking water, the shark absorbs some seawater (and salt) through its gills.
