Description
Octopus (Octopus sp.) on a coral reef. This marine invertebrate is a cephalopod mollusc. The octopus has a large brain and well-developed eyes (one at upper left). Eight tentacles form a ring around its mouth (a horny beak, not seen). It swims by jet propulsion or it crawls over reefs or the sea floor. It lives in a cave or suitable hole in the reef, emerging to hunt its prey. This is mostly crabs and lobsters, which it paralyses by injecting a poison. The body of an octopus will rarely exceed 40 centimetres in width. Octopuses can vary their skin colour and may eject a cloud of ink when alarmed. Photographed in the Red Sea.
