Clever Octopus
From Agence France-Presse: Octopus may have flexible arms, but it uses them in the same three-jointed way as vertebrates, a finding that sheds intriguing light on how limbs evolved, a new study says.
An Israeli research team filmed octopuses as they stretched out an arm from a hidey-hole in an aquarium to grab a piece of food with their tentacles and bring it to their mouths.
The octopuses, filmed about a hundred times, used a vertebrate-like strategy to carry out the complex movement.
