"My hope," Cousteau quips, "is that they think, 'Hey, that looks strangely like my retarded cousin from Australia!'" Cousteau spent more than 100 hours in the $100,000 submarine, custom-built by engineers at E.P. Industries in El Segundo, California, shooting video footage for a documentary film on shark cognition that´s due out by the end of the summer. Using a camouflage device, he believes, allows scientists to capture animal behavior in a purer way (most great-white footage is shot by divers inside a cage). To wit: Cousteau, posing as Troy, is the only person to ever capture on film a female shark attacking another female.
