Cuttlefish are intelligent molluscs capable of communication and learning. They are cephalopods with eight front-facing limbs. The Common Cuttlefish is native to the eastern Atlantic coast from Norway to southern Africa including the Mediterranean Sea. Mainly nocturnal, they can grow to 50cm long. Like other cephalopods, can rapidly change their colour and texture to match their surroundings for camouflage from prey or predators. They can spray brown ink to hide their getaway, an ink previously used by humans and after which the colour "sepia" is named. They have blue, copper-rich blood. Their internal bone used for buoyancy (cuttlebone) is washed up on beaches when they die and collected to supply calcium to cage birds.
