Pristiophoridei

The suborder Pristiophoridei, commonly known as saw sharks, comprises a small family of sharks characterized by a long, slender, saw-like snout equipped with sharp, tooth-like projections on each edge. These sharks are found in tropical and temperate marine waters across the Atlantic, Indian, and Pacific Oceans. They differ from sawfishes in having barbels on the underside of their saw and gill slits on the sides of their heads. Saw sharks typically grow to about 1.37 meters (4.5 feet) in length and feed on fish, using their saws to impale or stun prey. While they resemble sawfishes, they are distinct groups. Saw sharks are harmless to humans.12
