New York beaches reopened Monday morning following a shark attack that injured a lifeguard on Sunday. 

Lifeguards started work an hour early to look for sharks, and drones were used in the effort.

"Suffolk County FRES’ drone team was activated in a shark watch this past weekend at Smith Point County Park. The team assisted Suffolk County Parks after a County lifeguard was injured in a shark-related incident during a training exercise on Sunday morning," Suffolk County Fire Rescue and Emergency Services wrote Tuesday in a Facebook post. 

"Working in cooperation with the Parks Department and lifeguards on jet skis and paddleboards, the team provided continuous monitoring of the surf line on Sunday and Monday. The team’s livestreaming ability allowed parks officials, police and lifeguards to view real-time video from the drone operation," the post explained.

Suffolk County officials had closed a Long Island beach to swimming following the incident at Smith Point.

County Executive Steve Bellone said Sunday that the lifeguard had been playing the role of a victim during a morning training exercise when the shark bit him in the chest and hand.

"If you’re going to have an encounter with a shark this is probably the best scenario you could have," he said, adding the lifeguard received immediate treatment from other officials already engaged in the training. "We have never had an incident like this occur. Hopefully we never will again."

Bellone said there had been an additional shark sighting following the attack; it was not clear whether it was the same shark.

Zach Gallo, the 33-year-old lifeguard, told the New York Post on Monday that his survival instinct kicked in.

"I ripped back and just started hammer-punching, and I felt the rubber texture of the head. It felt like the size of a basketball," he recalled. 

Gallo, who required stitches, said he was grateful that his injuries were "minor" and that the shark was likely just "curious." 

Shark sightings have increased as warmer waters have sent them north earlier than usual.

In Volusia County – the "Shark Bite Capital of the World" – there were 17 shark bites recorded last season. 

Researchers and scientists say sharks get a bad rap and shark advocates have called for rebranding attacks as "interactions."
