Cam sharks live inside of seas?

    Sharks are too salty to live in the sea, the concentration of salt in sea water is only 3 to 4% and the overall saltiness of a shark is slightly greater than that of the sea. A shark can however survive in sea water. The fresh water from the sea will diffuse gently into their bodies and is then filtered by the kidneys and excreted out an opening called the “cloaca.” While the process is a nice one for the shark, too much fresh sea water would cause the kidneys to work overtime causing damage to the shark.
