Saving Sawfish
Season 6
Episode 604
The strange, prehistoric-looking Smalltooth Sawfish were once coveted by anglers as popular trophy fish. But habitat loss and overfishing have greatly reduced the animals’ range and landed them on the endangered species list. Today, the fish are limited to South Florida, where scientists are conducting research to save the species.
