These are the only purely freshwater sharks that have been discovered.

Any excess water in a shark’s body is filtered by the kidneys and excreted out an opening called the ‘cloaca’, located between the pelvic fins (the rearmost paired fins, behind the shark’s belly). It’s a very elegant solution to a significant environmental challenge.
