Today we watched part of the new Blue Planet 2, Episode one: One Ocean. The children found out about the incredibly intelligent orange-dotted tuskfish. Everyday he travels to the edge of the reef to find something special. In this episode, he finds a small clam, takes it back to his home-made coral kitchen and tries to crack it open using his tusks/jaw. It takes him a few attempts, but at last he does it! A fish that uses tools!
