A sandbar shark, Carcharhinus plumbeus, found off the coast of New Jersey, USA. The Sandbar Shark isn't plentiful but can be found in mid-Atlantic waters from May to September in the Delaware Bay area, which appears to be a mid-point in its migration to southern wintering and northern summering grounds. Sometimes called a Brown Shark because of its brownish color, the Sandbar Shark has a massive set of teeth that are triangular, serrated and razor sharp.
