Ha u^aiian Fishes 17 



This shark may be recognized by its teeth alone. The scientific name 

 Carcharodon comes from two Greek words which mean rough teeth. It 

 is the only fish in which the teeth are large, triangular, and serrate along 

 their edges. The body of this shark is a leaden gray color above, white 

 below, and has a keel on each side of the tail at its base. 



Little is known of the habits of this shark, suffice it to say that it 

 lives at the surface in warm seas, and is probably the strongest and most 

 voracious of all sharks. 



This shark is of no commercial importance today. Its teeth were used 

 in Hawaii in olden times for making many types of implements many of 

 which are on exhibit in the Bishop Museum in Honolulu. It is reported 

 to have been kapu to women in olden times. Of all of the sharks it has 

 the worst reputation, as a man eater. 



The niuhi is known to inhabit all of the tropical and temperate seas 

 of the globe. It is occasionally taken in both the Atlantic and Pacific 

 Oceans and along the shores of the Hawaiian Islands. It is cosmopolitan 

 in the temperate and tropical seas of the world.
