The Navy has dispatched some well-trained sea lions to help protect their ships. If any diver tries to approach an American ship – say to place an explosive under the hull – they may be in for the shock of their lives. The sea lions have been trained to carry a special clamp in their mouths which they can attach to a suspicious person, Commander John Wood, Special Operations Officer Naval Forces Central Command, told Reuters. The clamp is attached by a line to a flotation device which marks the swimmer for security personnel to apprehend him.

The US military is amazing.
