Sphyma Zygaena SmoothHammerhead Jaws
The hammerhead sharks can be recognized by their flat, rectangular shaped heads that look somewhat like a hammer. Their eyes as well as their nostrils are on the outer edges of their heads. As the hammerhead swims, its head swings back and forth giving it a broad angle of vision, broader than in other sharks due to the unique position of the eyes. It has a keen olfactory sense and the electro-receptors called Ampullae's of Lorenzini, also located on the head, are believed to aid in the search for prey. Of the eight species of hammerheads some, like the small Bonnethead (Sphyrna tiburo) an eater of crabs and other crustaceans, are of little no danger to human life, but the great hammerhead is. This shark can reach a length of eighteen feet (most individuals do not surpass twelve feet), and has been accused of attacks on people, although in many instances the culprit may have been another hammerhead species. Nonetheless, the great hammerhead is the most feared of its family. It is identified by a virtually straight margin of the head with an indentation in the middle, strongly serrated teeth, a high curved first dorsal fin and curved pectoral and anal fins. Its color is gray-brown above, light below without fin markings. The great hammerhead is circum-tropical, that is, it occurs all around the world in warm waters both inshore and offshore over continental shelves and island terraces. It often favors coral reefs and is known to migrate great distances, to higher latitudes in summer and back to the tropics in winter. The diet of the great hammerhead is broad and encompasses such animals as tarpon, sea catfishes, porgies, grunts, jacks, drums, groupers and snappers, other sharks, skates and rays, crabs and squid. Strangely, it seem undeterred by the poisonous barbs of stingrays and spines of catfish and these have been found imbedded in its mouth, throat and tongue. It is a prolific shark, the females bearing alive litters of a dozen to more than 40 pups. In the northern hemisphere, birthing occurs in the spring and summer.
