The common cuttlefish is a highly evolved mollusc with large eyes, tough jaws, 8 arms, 2 retractable tentacles and an internal cuttlebone [1]. The body is flattened and oval in shape, with lateral fins running the entire length of the body [1]. The cuttlebone is made of calcium carbonate and is used to control the animals’ buoyancy. The cuttlefish is capable of changing colour and texture very rapidly, this may be used in sexual or competitive behaviour or to camouflage.
