Pirhana 3: Armed and flippery.

Trained dolphin snipers set free by hurricane.

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.

'My concern is that they have learnt to shoot at divers in wetsuits who have simulated terrorists in exercises. If divers or windsurfers are mistaken for a spy or suicide bomber and if equipped with special harnesses carrying toxic darts, they could fire,' he said. 'The darts are designed to put the target to sleep so they can be interrogated later, but what happens if the victim is not found for hours?'

Anyone remember the very bad movie Pirhana and it's even worse sequel, where the pirhanas are crossed with flying fish? Well, let's hope those flying pirhanas don't meet up with the dart-shooting dolphins and have any young'uns.
