take a look at a spinner shark. very common off our coast bigger ones like that one will have black tips on their fins also most true black tips the dorsal fin will have a dark black tip
all three are easy to confuse except the bulls will get much bigger
Could be an Atlantic Sharpnose, you can tell the difference between them and a blacktip by the tail fin but it's cut off in your picture. Some freinds and I caught 4 of them on Elmer's Island a couple weeks ago.
