How Wildlife Photographers Use "Spy Creatures"

In this short film, wildlife director John Downer explains how wildlife filmmaking has changed in recent years with the advent of miniature cameras. The craziest part starts around 3:30, when he begins a discussion of animatronic camera-bots, which are basically cameras in remotely operated pseudo-animal bodies. Downer calls them "spy creatures." There's a Spy Tuna, a Spy Turtle, a Spy Clam, various Spy Dolphins, a Spy Penguin, you name it. Nature photography combined with bizarro robots? Sign me up!
