If you were dying to know how shallow water octopus migrated to the deep sea, wonder no more. A group of researchers travelling around the world to record and investigate new life a-la-Darwin have discovered a whole new menagery of critters including giant bacteria, giant starfish and most importantly the proto-octopus. DNA evidence had supported the notion that deep sea octopus had originated from a single common ancestor about 30 million years ago and the octopus which was found in shallow seas around Antarctica seemed to fit the bill as the grand-daddy of them all. Ecologists will want to follow this link to read more about how octopus took the big dive.
