Crittercam is a research tool used by National Geographic scientists to observe and study animal behavior in the wild. It’s a video and audio recording device which is clipped to the animal and later released (no animals are harmed). Crittercam is used successfully on both land and sea animals, such as sharks, turtles, lions, seals, sea lions and tree kangaroos.
National Geographic’s Crittercam home page has a wealth of information about the Crittercam program, as well as many fascinating Crittercam videos. Among my favorites is the video below. Filmed in Western Australia’s Ningaloo Reef, Crittercam takes you along for a wild ride with a whale shark.
