Pristiophorus schroederi

Sawsharks have a long and flat saw-like rostrum studded with teeth. They are small slender sharks with flattened heads and a pair or barbels beneath the rostrum. They are found only on continental and insular shelves of the northwest and southeast Atlantic, west Indian and west Pacific Ocean, in shallow water in temperate regions, deeper in the tropics. These sharks are ovoviviparous (aplacental viviparous) with litters averaging 7 to17 pups. Sawsharks are often confused with sawfishes which are batoids (rays).

WHAT TO LOOK FOR
A slender shark with a very long, narrow, tapering rostrum (preoral length about 31-32% of the shark’s total length) with barbels halfway between the mouth and rostral tip, and a concave, pre-barbel edge.
