A shark by any other name, ....

Attached are photos showing three different shark species including: sandbar, hammerhead, bull. Hammerheads are easily recognized by their distinctive heads and bull sharks have a solid grey skin, but very wide thick bodies. I am pictured below with an Atlantic sharpnose shark which grow to much smaller sizes as adults compared to the sharks species listed above.

Some sharks we caught were too large to be brought on board, so they were tagged from the ship's deck. Tags need to be inserted almost anywhere on the dorsal surface of the shark except the fin or the gills. For each shark see if you can determine the shark type and gender.
