Dolphins Gang Up on Harbor Porpoise

The Pendeen Gig Club was out for a social row on October 9 when they realized they had seen two dolphins attacking a harbor porpoise. Various members can be heard saying "aww.." for the first half of the video, before it starts to dawn on some of them that "they've killed that." Most of the group agrees the harbor porpoise is dead by the end of the video, with one member audibly trying to guess what has happened. "If it was a fish they would eat it, [but] if it is a dolphin then they are trying to pull it down to help it," a woman can be heard saying in the closing seconds of the video. This is not a unique situation, according to a BBC report, with dolphin attacks on porpoises accounting for about one death a year on average, according to the Cornwall Wildlife Trust.
