A young American on vacation with her family was killed in a shark attack Wednesday. Jordan Lindsey, 21, was snorkeling in the Bahamas when cops say her parents saw a swarm of three sharks coming at her. They quickly engulfed her, fatally mauling her. The nightmare took place off Rose Island. Curator and co-founder of the Long Island Aquarium Joe Yaiullo spoke to Inside Edition about how to stay safe in the water during shark season.
