Saw Sharks

Order: Pristiophoriformes

Sawsharks resemble sawfish, with a long, toothy, sword-like snout to find and slash their prey. They have long nasal barbels, or mustache-like appendages, extending from the middle of the long snout that are very sensitive. The Sawshark's barbels, together with electro-receptors (ampullae of Lorenzini) on the underside of the saw, are used to sense prey buried in the sand. Sawsharks use the saw to uncover and disable the prey, which they then take into their small mouths.
