The spiny dogfish is a small shark that averages about two feet in length and three pounds in weight. It is called spiny because of the presence of a prominent spine on the boarder of each dorsal fin. The species has a wide distribution in the North Atlantic, occurring plentifully on the American and European shores, as well as in the Mediterranean Sea. The fish swim in enormous schools and are constantly in motion. The dogfish has no economic importance but is universally used for dissection in the zoological laboratory.
