of shark found along the coast of South Carolina; 40 were once taken in 

 one dav with seines on Galveston Island, Texas. A relativelv small shark, 

 rarely growing more than 5 feet in length, the Bonnet usually loiters 

 around shore and sometimes appears near wharves. It ranges from south- 

 ern Brazil to the southern shores of North Carolina, and occasionally 

 strays to New England. On the Pacific coast, the Bonnet cruises from 

 southern California to Ecuador. It is also found in the Gulf of Mexico. 



Great Hammerhead 

 (Sphyrna tudes Va.\enciennes, 1822) 

 This is the largest Hammerhead in the Atlantic and possibly the 

 largest Hammerhead in the world. It is known to grow to 15 feet. It 

 is found throughout the world, from the warm waters of the Atlantic 

 to the Gulf of Mexico and the west coast of Central America; from 

 Hawaii to Australia and Indo-China; along the shores of India and in the 

 Gulf of Arabia. In India, it is sometimes called the Horned shark because 

 the projecting lobes are looked upon as horns by natives who are more 

 familiar with cattle, presumably, than with carpenter's tools. 



Common Hammerhead 



(Sphyrna zygaeim Linnaeus, 1758) 

 A fast, lively shark, the Common Hammerhead has been seen chasing 

 Sting rays, which appear to be one of its favorite meals. One of these 

 Hammerheads once put up such a fight when hooked that it died of 

 exhaustion. It eats other sharks, and is known to have attacked men and 

 boats. In the summer, great schools of these Hammerheads migrate 

 northward along the Atlantic seaboard. Many linger around Charleston, 

 South Carolina. Others visit Maryland, New Jersey, and New York 

 waters, sometimes entering New York harbor. Most of the sharks in 

 these annual warm-\\eather migrations are small and were probably 

 born shortly before the summer trek began. Dozens of little Hammer-
