Somewhat old news but... The Defense Advanced Research Project Agency is working on electronics to control sharks for military use.
I have an idea for the job ad :)
"Electronics Engineer Wanted Do you hate sharks but love electronics? Join DARPA in the exciting field of remote controlled cyborg stealth zombie sharks! Turn Jaws into a playful puppy or send it on a kamikaze mission to blow up a ship. Surprise stranded sailors when they're rescued by a shark. ("Oh man..I thought I was a gonner when I saw that fin.") Counter terrorism and make 'shark spies' that patrol the oceans. Send your resume to DARPA today! Some fish control experience required."
Who gets these weird ass electronics jobs and how's the pay?
