Researchers tracking migration of half-ton shark swimming up and down the East Coast

An ornery nice white shark is being tracked up and down the East Coast–most lately swimming off the North Carolina shore.

The shark is known as Ironbound. He is a 20-year-old apex predator measuring over 12 ft lengthy and weighing in at round 1,000 kilos. However his dimension is just not what caught the eye of researchers; that was his mood.

“That’s what struck us with Ironbound. It wasn’t really his size. He was just a very determined animal to deal with. He was very bit up from other large sharks he’d been tangling with,” Ocearch founder Chris Fischer stated.

Ironbound’s tracker pings every time he involves the floor. It final pinged on Tuesday, Could 10, off the coast of the Cape Hatteras Nationwide Seashore alongside the Outer Banks of North Carolina. Two weeks earlier than that, he was swimming off the New Jersey coast.

Fischer stated that is one thing they see yearly with nice whites. The sharks migrate south for the winter in search of hotter water and north throughout the summer season in search of plentiful searching grounds.

Nonetheless, these migrations aren’t uniform. Generally a shark will head north too early and wind up in water that is too chilly; they will then rapidly flip round and head again south for a short time longer.

Ocearch’s mission in tracking the ocean’s apex predator is to be taught extra about them and assist destigmatize them

For instance, no person formally is aware of the place nice white sharks mate. The main principle is someplace off the coast of North Carolina, however Ocearch hopes their work might help shed extra mild on that thriller.

As well as, tagging sharks like Ironbound or Mary Lee–the 4,000 pound feminine tagged again in 2012–helps present people who these animals are all the time close by however very hardly ever hurt people.

The truth is, there have been solely 73 unprovoked shark bites in the world in 2021. Ocearch credit Mary Lee and the continued work by numerous shark researchers.

“I think she did more to undo what Jaws has done than any other shark in the world, because people started to realize that they’re swimming all around us, if they thrive we thrive and appreciate them more like lions,” Fischer stated.
