There was a scare for swimmers who were trying to escape the heat Saturday morning.

When Ian Connett was walking along a dock in Quogue Saturday morning, he spotted two fins in the water. He first believed they were two fish, but then he realized it was something bigger.

Connett says after he saw the 10-12 foot shark swimming in Penniman Creek, he called the police. He says the shark didn't bother anyone, but it was swimming in an area where people paddle board, sail and swim.

After the shark sighting in Quogue, people have been on the lookout for more. On Saturday at Field 1 on Jones Beach, swimmers had to get out of the water due to an unconfirmed sighting. A shark expert says he doesn't believe there are more sharks swimming in Long Island waters, they're just being reported more.

"This may be more common than we initially thought it might be, prior to everyone having cellphones and cameras to document this stuff," says Greg Metzger, a shark researcher for The South Fork Natural History Museum.

Metzger says it is unusual for a shark that big to be in a creek or bay and not the ocean. He guesses it was following a school of fish to try to get something to eat.

Experts say it's hard to tell what kind of shark it was based on the picture.

According to shark researchers at The South Fork Natural History Museum, there have been 12 negative interactions between people and sharks in New York waters in the last 100 years.
