A shark westbound in Cape Cod Canal.
I wondered if it was an ocean sunfish. The local fishermen assured me
it was a shark (rigid fin) and not a sunfish (floppy fin).

Thanks Paul. Although I must give credit to the fishermen there for
pointing it out. They were pretty excited. I suspect the fish they
were trying to catch were also pretty excited.
