Day Octopus (Octopus cyanea). (order Octopoda). This marine invertebrate is a cephalopod mollusc. The octopus has a large brain and well-developed eyes. Eight tentacles form a ring around its mouth (a horny beak,not seen). It swims by jet propulsion with its body sac (upper left),or it crawls over rock surfaces. It lives in a cave or a crevice in rocks,emerging to hunt. Its prey is mostly crabs and lobsters,which it paralyses by injecting a poison. Some octopuses can reach a length of over one metre. Octopuses can vary their skin colour and may eject a cloud of ink when alarmed. Photographed in the Red Sea Israel | |
