A recent BBC report tells of a British magazine, the New Scientist, that says Pentagon scientists are planning to turn sharks into “stealth spies” capable of tracking vessels undetected. Apparently, they aim to remotely control the sharks by implanting electrodes in their brains, “to exploit sharks' natural ability to glide through the water, sense delicate electrical gradients and follow chemical trails”. The next step for the Pentagon scientists will be the release of blue sharks with similar devices into the ocean off the coast of Florida.
