Bob Hueter, Chief Scientist of the nonprofit Ocean, said: Told to CNN About search.
Ocearch tags and tracks great white sharks (Great white shark) To better understand their elusive transition. A harmless device called a SPOT tag is attached to the dorsal fin and relays the position of the shark to the Global Positioning System (GPS) satellites. The tag is designed to fall after a few years.
There are some errors in the tracker. This means that if a shark emerges within the range of GPS satellites, the exact position of the shark may be off by a few feet or meters.
“The error bars can be the difference between one side and the other side of Long Island,” said George Burgess, a marine biologist and honorary director of the Florida Program for Shark Studies at the Florida Museum of Natural History. , Told live science In 2019.
Hueter told CNN that Ocean had tagged a 17.5-foot (5 m), 4,000-pound (1,814 kg) great white shark. This means that the Ironbound is reasonably sized.
Ironbound has traveled an estimated 13,000 miles (20,921 kilometers) since it was first tagged. Most recently, he was discovered on May 3rd. Ocearch dataWhen an adult man was far away in the Atlantic Ocean, just east of Philadelphia.

They moved for food and breeding, and researchers recorded them in temperate and tropical waters around the world. They often appear offshore in countries such as the United States, Australia and South Africa.
According to 2018, great white sharks are on the verge of extinction and their populations are declining. evaluation According to the International Union for Conservation of Nature (IUCN). Sharks are not technically endangered, but they are at risk of gaining their place due to human threats such as overfishing.
