Boston University marine biologist Jelle Atema has made progress converting sharks to “remote control” so that they could be outfitted with sensors and sent on spying machines. In a project funded by the Defense Advanced Research Projects Agency (DARPA), Atema implanted sharks with electrical stimulators that trick their brains into smelling food. Using the stimulators, he was able to “steer” the sharks around a tank. From Boston University’s Alumni e-Newsletter where a video demonstration can be seen:
For decades, the navy has used dolphins and sea lions to patrol harbors, salvage expensive hardware, and locate potential sea mines. Indeed, mounting chemical, auditory, or visual sensors on a shark is the easy part. The challenge is finding a way to steer sharks over long distances. Over millions of years, sharks have evolved to pursue one particular target of opportunity – lunch – and military commanders would need a way to override that instinct in order to dispatch their shark spies to areas of strategic interest… The military has since made the research classified, and it is now run out of the Naval Undersea Warfare Center in Newport, R.I. But Atema is seeking new funding sources to continue his work on sharks, with potential civilian applications in mind – such as tracking fish populations, changes in ocean temperatures, or chemical spills.
