National Geographic delights us with this first ever video of sea lions hunting a large octopus. The footage is from a project intended to help save the endangered sea lions, in part by uncovering where and how the animals eat. It has been realized thanks to a Crittercam, the small package of instruments including a camera that can be attached to a wild animal to study its behaviour in the wild. Crittercam was invented by National Geographic marine biologist Greg Marshall in 1986. Since than it has been employed in studies on over 40 marine and terrestrial animals and on the Emperor Penguin obtaining the footagr used in the Oscar-winning documentary March of the Penguins.
