Sawshark

A sawshark or saw shark is a member of a shark order (Pristiophoriformes ) bearing a unique long, saw-like rostrum (snout or bill) edged with sharp teeth, which they use to slash and disable their prey. There are ten species within the Pristiophoriformes, the longnose or common sawshark (Pristiophorus cirratus), shortnose sawshark (Pristiophorus nudipinnis), Japanese sawshark (Pristiophorus japonicas), Bahamas sawshark (Pristiophorus schroederi), Warren's sixgill sawshark (Pliotrema warreni), Anna's sixgill sawshark (Pliotrema annae), Kaja's sixgill sawshark (Pliotrema kajae), African dwarf sawshark (Pristiophorus nancyae), Lana's sawshark (Pristiophorus lanae) and the tropical sawshark (Pristiophorus delicatus). Sawsharks are found in many areas around the world, most commonly in waters from the Indian Ocean to the southern Pacific Ocean. They are normally found at depths around 40–100 m, but can be found much lower in tropical regions. The Bahamas sawshark was discovered in deeper waters (640 m to 915 m) of the northwestern Caribbean.
