"Remote controlled cyborg shark-bots... Engineers funded by the US military have created a neural implant designed to enable a shark's brain signals to be manipulated remotely.....a number of groups around the world that have gained ethical approval to develop implants that can monitor and influence the behaviour of animals, from sharks and tuna to rats and monkeys."

That's frickin awesome!
An interesting application would be to put that in some tuna so that then
you can make the whole school of tuna come to where your nets are...
