Dolphins have been used for decades by the military for underwater/undercover operations, but who knew that some of them were equipped with dart guns? Or that several dozen such-equipped dolphins could be missing since the recent flooding in the Gulf? From The Guardian UK:
Armed dolphins, trained by the US military to shoot terrorists and pinpoint spies underwater, may be missing in the Gulf of Mexico. Experts who have studied the US navy’s cetacean training exercises claim the 36 mammals could be carrying ‘toxic dart’ guns. Divers and surfers risk attack, they claim, from a species considered to be among the planet’s smartest. The US navy admits it has been training dolphins for military purposes, but has refused to confirm that any are missing.
