Remote-controlled shark spies

The New Scientist reports that the military has gotten so-called "ethical approval" to put implants into animals that will allow the military to control the animal.

". . . the Pentagon hopes to exploit sharks’ natural ability to glide quietly through the water, sense delicate electrical gradients and follow chemical trails. By remotely guiding the sharks’ movements, they hope to transform the animals into stealth spies, perhaps capable of following vessels without being spotted."
