This seems like a horrible idea.

Pentagon Mulls 'Stealth Sharks'

The Pentagon is funding research into neural implants with the ultimate hope of turning sharks into "stealth spies" capable of gliding undetected through the ocean, the British weekly New Scientist says.

The research builds on experimental work to control animals by implanting tiny electrodes in their brain, which are then stimulated to induce a behavioral response.

Now I'm pretty sure that the Pentagon officials don't watch a lot of Scifi channel original movies but here's how this thing usually goues: Government genetically modifies animal > animal then finds college kids on spring break > chasing;hurting;eating >the one scientist/sherrif/random guy noone listened to saved the day. Anyway, like I said, horrible idea.
