Cb6H 3 ' 



We sequenced a tiger shark from the Gulf of Mexico 

 and found 46 nucleotide differences between our se- 

 quence and that of Martin and Palumbi (1993). This 

 difference is greater than that seen between all pairs 

 of species in this study and is clearly too large of a 

 difference to be explained by intraspecific polymor- 

 phism. Because our observed restriction patterns for 

 tiger sharks from the Atlantic and Pacific match pre- 



dictions made from our tiger shark sequence, our se- 

 quence for the tiger shark is likely correct, and part 

 of the sequence listed in Martin and Palumbi (1993) 

 is not that of tiger shark. 



The remaining eight species — bignose, blacktip (C 

 limbatiis), bull (C. leucas), dusky, silky (C falci- 

 formis), scalloped hammerhead, great hammerhead, 

 and lemon sharks — exhibited restriction patterns
