All species of Sawfish are notorious for having a long snout with a sawblade like pattern of teeth, which extends to great length. They use this snout to thrash about and make a big mess of its prey (crustaceans and other bottom dwellers) by slicing it into small pieces. Its snout is also used to dig.

Sawfish (with the exception of the dwarf species) can grow up to 25 feet long, and weigh a ridiculous 5000 pounds.
