A large migratory white shark weighing up to 1,000 pounds (453 kilograms) off the coast of New Jersey on April 28 in search of rich northern fishing grounds. Researchers named the shark “Ironbound” when it was first caught and marked in 2019, as it was found near West Ironbound Island near Lunenburg, Nova Scotia. A 12.4-foot (3.7 m) shark migratory at the time of satellite observations.
“The mating season is over, we think, and Ironbound is on its way north to enter a good restaurant and expand again the following year,” Bob Hueter, a senior nonprofit scientist at Ocearch, told CNN about the findings.

Ocearch tags also trace large white sharks (Carcharodon carcharias) in an effort to better understand their difficult migration. A harmless tool, called the SPOT tag, is attached to the dorsal fin and transmits shark location to the global positioning device (GPS) setting. The tag is designed to fall out after a few years. The trackers have a slight error limit, which means that the correct shark area can be removed by a few feet or meters when they reach the GPS satellite distance.
“That error bar could be the difference between one side of Long Island and the other,” George Burgess, a marine biologist and director from the Florida Program for Shark Research at the Florida Museum of Natural History, told Live Science in 2019.Hueter told that Ocearch has marked large white sharks 17.5 (5 m) in length and weighs 4,000 pounds (1,814 kg), meaning Ironbound is of limited size.Ironbound has traveled approximately 13,000 kilometers (20,921 kilometers) since its first marking. Most recently, he was spotted on May 3, according to Ocearch data, when an elderly man was far from the Atlantic Ocean, east of Philadelphia.
Great whites are popular among the public for their appearances in films such as “Jaws” (1975) and Sharknado (2013), as well as those subsequent franchises. That being said, their behavior is not at all close to the way the films portray them.“White sharks are often portrayed as‘ mindless killers ’and‘ lovers of human flesh. However, this does not seem to be the case; we look like their food, ”said Laura Ryan, a postdoctoral researcher at Macquarie University in Australia, who previously told Live Science.
They migrate in search of food and breeding, and researchers have documented them on the cool, tropical oceans of the world; they often appear on the coasts of countries such as the U.S., Australia and South Africa.Large white sharks are in danger of extinction and are declining in number, according to a 2018 study by the International Union for Conservation of Nature (IUCN). Although sharks are not technically endangered, they are at risk of contracting the disease because of human threats such as overfishing.
