The urinary bladder is situated behind the Vent (Anus) on the fish. Just as it is on humans, it is there to release any unwanted waste from the body. Fish have two bladders, one is a swim bladder and the other is the urinary bladder. Do not get these mixed up.

Fish do not use urea to get rid of their nitrogen like mammals do, but instead use NH3 Ammonia.
