A shark tracking map shows more than a dozen predators lurk along the northeast coast.

More than a dozen giant dangerous sharks are currently swimming around the northeast coast and are expected to remain here until autumn.

Shark researchers report a massive 528-pound white shark off the coast of Cape Cod, while more than 14 sharks lurk in the waters around Long Island.

Officials fear that as the number of attacks rises, attacks will become more frequent, and one of them happened just over the weekend.

A lifeguard was bitten on Sunday morning at Smith Point Beach and taken to the hospital to be treated for his injuries.

About 14 sharks were swimming around Long Island as of Monday afternoon, the largest of which is a 125-pound shortfin mako shark named “Princess”.

Further north, at Cape Cod, another shark was spotted just 150 feet from Race Point beach from a helicopter flying above.

More than a dozen giant dangerous sharks are currently swimming around the northeast coast and are expected to remain until autumn.

Toward the end of spring, the sharks leave their winter homes in the south and head for warmer waters in the north, causing a massive migration that settles on the east coast beaches, which are also heavily populated by visitors until late September.

Scientists have warned visitors to Cape Cod not to get tired swimming in the bay as at least 100 shark migrations could be seen in the region this summer.

Researchers have tagged more than 280 great whites off the Cape since 2009, scientists say, with nearly 230 of those tags still active and sending data on shark movements.

Predator tagging allows the team to better understand where sharks are likely to appear, as well as what time of day they are most active.

The Princess, a 528-pound shark, appears to be the largest lurking around Cape Cod.  Labeled OCEARCH, this young female is over 10 feet long and was first seen last year.

At least six OCEARCH-tagged sharks are swimming around the New England Peninsula.

OCEARCH is a data-driven organization created to help scientists collect ocean data.

Greg Skomal, a government marine biologist who has studied great whites in the region for decades, said the animals still tend to be concentrated on the Atlantic side of the headland, where they feast on a thriving seal population.

He advised beachgoers to be extra vigilant when sailing offshore, where the shoreline quickly recedes into deeper waters.

Traveling a little further south, you will see another large shark concentration located around Long Island, New York.

However, these animals are much smaller than those that live in the waters of Massachusetts.

More than 20 species of sharks live in the waters of Long Island, of which the brown shark is the most common.

It’s unclear which shark bit the lifeguard over the weekend, but what is certain is that the animal swam very close to the coastline.

Zachary Gallo was playing the victim during a drill when a five-foot shark bit him in the chest and arm at 10:15 a.m. at Smith Point Beach in New York.

The beach was closed after the attack but reopened at 10:00 am on 4 July.

He received stitches in his chest and Suffolk County authorities closed a Long Island beach to swimming on Sunday after an unprecedented shark attack.

The rescuer said that as soon as he felt the attacker’s texture, he knew it was a shark.

“I felt a sharp, sharp pain, and as soon as I felt the rubbery texture, I knew it was some kind of shark,” Gallo told CBS.

He said: “I hit the shark three times. I went boom, boom, boom. I think in the third he turned around and hit me in the chest.”
