Finally ... RoboShark!
Noryungi writes "Cousteau's grandson has built a robotic replica of a great white shark to better observe these animals in their natural environment. The robot-slash-submarine is able to mingle with the great white, and not draw their attention, thanks to a closed-circuit pneumatic propulsion system and cleverly disguised cameras. Do not miss the nice pictures next to the Wired article. Let the Dr Evil joke begin!"
AFAIK sharks (like sting rays) are extremely sensitive to electric fields. They are so sensitive in fact that there were some shark repellant devices a few years back that basically just periodically zapped the water at a voltage level that wasn't noticed by people but scared off sharks. How then, can this mechanical device with electronic cameras in it fool a shark into acting naturally when its giving off a strange electric field signature?
