Above the Shortnose sawshark

1. There are seven described and two undescribed species of sawshark known.

2. Sawsharks have a pair of long barbels about halfway along the snout. They have two dorsal fins but don’t have an anal fins and range up to 170 centimeters (5.6 ft) in length. Some sawsharks have 6 gills and some have more.

3. The Sawsharks feed on fish, squid and crustaceans it depending on species. They cruise on the bottom and using the barbels and ampullae of Lorenzini on the saw to detect prey in mud or sand then hit victims with side-to-side swipes of the saw crippling them.

4. Although they are similar in appearance sawsharks are distinct from sawfish. Sawfish have a much larger maximum size and lack barbels and have evenly sized rather than alternating sawteeth and have gill slits on their undersurface rather than on the side of the head.
