Sharks will go to the bottom in shallow waters and just lie there, usually holed up under rocks or in caves. But no one's really sure if they're resting or if they're doing this for some other, as yet unknown, purpose. Yes, Sharks do sleep at night by resting itself on the seafloor as if it's lying on a bed.
But they do have extra large livers, which provide some buoyancy and help keep them sinking to the ocean floor. But fresh water changes how much buoyancy the shark's liver can provide. The researchers found that when sharks swim in fresh water, they are two to three times less buoyant than when they swim in salt water. In order to keep afloat the same way they do in salt water, sharks would need livers eight times as largeâunrealistic for an organ thatâs already the largest in a sharkâs body.
