Researchers from the Atlantic White Shark Conservancy, the New England Aquarium and the Massachusetts Division of Marine Fisheries published their findings in the journal Environmental Biology of Fishes last year.

Dusky sharks migrate to the Gulf during the winter. Between 2003 and 2022, the Mote aquarium did not catch a single dusky shark, Chapman said. But in December 2022, biologists caught two dusky sharks in a row -- both females longer than 10 feet -- further proof that the species is rebounding.

Ever since, Mote researchers have been catching and tagging between two to six dusky sharks every winter, according to Chapman.

\"We've started to see them come back, which is fantastic,\" he said.
