Rambo, the Octographer
Rambo is the world's first professional shutterbug. Aquarium staff at the Sea Life Aquarium trained one of their octopus (via operant conditioning) to push a red button, which is connected to a digital camera's shutter button in an underwater camera housing. Aquarium visitors can pay $2 for photos taken by Rambo, with proceeds going towards conservation programs.
Here's a video (produced by Sony, who supplied the camera) of Rambo snapping away.
