(Narragansett, RI) -- Swimmers exited the water at two Narragansett beaches on Tuesday afternoon after a fin was sighted. The Rhode Island Department of Environmental Management says the Roger Wheeler and Salty Brine beaches were closed for about an hour. However, it was determined the fin was not from a shark. The Atlantic Shark Institute tells WPRI-TV several boaters were able to determine it was a sunfish.
