sawshark

Member of two genera of sharks. They grow to 1 m/3.3 ft long including the long, sawlike, toothed snout, which is used to attack prey. They are not dangerous to humans.

Classification Pliotrema and Pristiophorus, are in the family Pristiophoridae of order Pristiophoriformes, subclass Elasmobranchii, class Chondrichthyes.
