National Geographic has a terrific device known as the Crittercam. The penguin on the left is wearing one. He’s not the only animal that has. It’s been worn by a variety of animals, including humpback whales and a bear cub.
The idea for the Crittercam came to marine biologist and filmmaker Greg Marshall in 1986. He was on a diving trip when a shark approached and quickly took off in the opposite direction. It occurred to Marshall that if he could put a camera on the shark where the sucker fish often hung, he could see the world from the shark’s perspective, without disturbing the shark.
Fast forward to 2014. Marshall is head of the Remote Imaging Program at National Geographic. Crittercam is here to stay. You’ll find more info and links to videos on their site.
