"Sharks with Frick'n Laser Beams" is closer than you think.

clipped from sharkdivers.blogspot.com Apparently DARPA, our military's mad science wing has been exploring implants in the brains of sharks that "steer them" from a remote location like, sorry for the pun, Predator Drones. Seriously. Darpa military research is currently exploring ways to use electronic stimulus to control shark behavior and movement. In fact, scientists at Boston University have already developed brain implants that can influence the movements of dogfish (members of the shark family) by "steering" them using a phantom odor. The military objective of controlling the movement of sharks is outlined in the New Scientist Magazine as follows; "By remotely guiding sharks' movements, the military hopes to transform the animals into stealth spies, perhaps capable of following vessels without being spotted. The Pentagon hopes to exploit the ability of sharks to glide quietly through the water, sense delicate electrical gradients and follow chemical trails.”
