Shark ID?

[Take a kid fishing]

Fluked in about 35 foot if water off IBSP. Pretty good with 2 keepers and plenty of action on shorts, robins and small blues. At around 10AM we had a 6 foot shark swim past our boat like we were not even there. Dark gray in color with a short dorsal and tail fin visible as it swam by. Tried to get a picture but it all happened too fast. May be a long shot but Any idea what species? Not expecting anything dramatic just curious.

If it had a long whip like tail it could have been a Thresher. If not my next guess would be a Brown Sharks since they are are known to come in close to the beach.

Short dorsal and fin tail , maybe , short fin mako , baby ! Supposedly tuna on beach of seaside ...in surf according to jersey tackle face book

I would say brown shark or dusky, mako's look blue in color

I would think Brown is the right call but i would not be shocked if it was a bull shark. They always come inshore and rarely swim deep. Did you notice if there was a 2nd smaller dorsal fin? Pay attention to Dicovery Channel this week and i am sure you will see it. Bring on shark week!

Have caught threshers before so I am sure if was not that and it did not have a pronounced second dorsal. Looked at some photos and the dusky dorsal looks about right. ???
