Sharks are filter feeders and sieve tiny bits of plankton and small animals from the water through the gills as they swim with wide-open mouths. They do not drink water. The blood and tissues of sharks are salty containing high levels of urea, and other salts. Sharks basically are saltier than the sea. Sharks absorb pure water from the sea by Osmosis (through their gills). It's a process where water flows across a semi permeable membrane from an area of higher concentration of water to an area of lower concentration to equalize concentration levels. Sharks can secrete extra salts through their rectal gland. Most sharks can't live in fresh water with the exception of bull sharks which can lower their salt level to enter into fresh water.
