Sharks mistaking feet for fish are likely behind Long Island attacks

A series of five shark attacks in two weeks on New York’s Long Island probably has many beachgoers in the Northeast hesitant to wade into the water.

But the sharks aren’t targeting humans — they’re after fish.

A sand tiger shark nursery located just off the Long Island coast and an abundance of bait fish close to shore could explain the recent string of unwanted encounters, according to Florida Program for Shark Research Program Director Gavin Naylor.
