A record amount of shark attacks has happened on Long Island this summer.

Marine experts say over the past century, there have been 13 total attacks in New York. Five of those were this year alone.

The Department of Environmental Conversation says several shark species are always lurking in New York waters.

Chris Scott, DEC supervising marine biologist, says there is more food for sharks to eat.

"The reason we're having more sighting is because we have these large schools of fish near shore these last couple of years," Scott says. "So, they're taking that prey population to feed."

Experts stress that the risk is still for people to come in contact with a shark.

Swimmers are advised not to go into the water during dusk, dawn or nighttime since those are peak feeding times.
