According to the Estrecho Marine Biology Station of the University of Seville, the entangled sunfish was discovered off Cueta, on the north coast of Africa, on Oct. 4.

“We tried to put it on the 1,000-kg (2,204.6-pound) scale but it was too heavy. It would’ve broken it,” the station’s Enrique Ostale told Reuters. “Based off its corpulence and compared with other catches, it must’ve weighed around 2 tonnes (4,409 pounds).”
