WATCH: Another Shark Sighting Halts Swimming At Jersey Shore Beach

For the second time this week, lifeguards called bathers out of the water after spotting a shark near a Jersey Shore beach.

Swimmers in Avalon were called out of the water twice over a three-hour span because of a shark sighting. Lifeguards said the shark appeared to be about 4-feet-long and was in waist-deep water, according to Philly Voice.

Twitter users posted photos and videos of the water being evacuated, and showing the fin of the shark out in the ocean (see video below).

Another lifeguard says he saw what appeared to be a shark fin off Margate on Monday morning, and he called swimmers out of the water after seeing the fish, according to WNBC-TV.

It was unclear if more signs of the shark were found, but the sightings come in the wake of a rash of shark attacks off the coasts of the Carolinas, according to the report.

The Margate shark was spotted off the Gladstone Avenue beach around 1 p.m. Monday, beach patrol told NBC10.

Lifeguards jumped into a rowboat and went out to investigate the sighting, saying the shark appeared to be chasing a large school of fish nearby, according to the report.

No one was injured, and swimming was allowed again about an hour later, according to the report.

The Marine Mammal Standing Center in Brigantine has acknowledged that the sightings are more common than usual, pointing to a photo that’s been going around social media of a newborn bottlenose dolphin, and noting that dead floating animals are very likely to have shark bites.

But Robert Schoelkopf, director of the center, said people should not be so alarmed by videos of sharks. Sharks attacks, he said, are less common than “bathtub falls.”

“But they’re [sharks] there all the time. People are just getting more fascinated by it,” he said. “Now people are seeing it and they’re freaking out about it.”
