However, since late July, the normally social animals have been intentionally attacking sailboats off the coasts of Spain and Portugal. The strange behavior first surfaced on July 29, 2020, when a 46-foot boat was repeatedly attacked for almost an hour by nine orcas, causing the boat to rotate(旋转) 180 degrees and having its engine switched off. Since then, over 30 more similar incidents have been reported. On September 23, 2020, Spain's government banned boats of less than 50 feet in length from sailing in the 60-mile stretch of the Atlantic coastline between Ferrol and the Estaca de Bares Cape, where the attacks have been occurring. Researchers across the world are trying to explain the orcas' behavior. Some believe it could be a result of the overfishing of the bluefish tuna - the orcas' primary food source -which has left the area's killer whales starving and unable to feed their babies. "I saw them look at boats carrying fish. I think they know humans are somehow related to food shortages, "says Ken Balcomb, senior scientist at the Center for Whale Research in Washington, US A. The environmentalists believe the sudden increase in boat traffic and fishing activities, after months of absence due to restrictions on human activity last spring, could also be contributing to the agitation.
