Octopus Constructs Shelter

Apparently, Australian scientists discovered that Indonesia's veined octopus collects shells for shelter. While octopuses do use shells for shelter, these ones actually carry two coconut halves up to 65 feet and put them together to build a shelter. It's the actual carrying and plotting that makes scientists believe this is the first sign of tool use in an invertebrate. Check out the YouTube video below to see this 8-legged squid at work.
