Cuttlefish swim by propelling themselves backwards or by hovering, gently moving their fins. They can also change their buoyancy and move up or down in the water column.
Cuttlefish camouflage themselves to hide from predators and to ambush prey. This camouflage is seen in the changing of colours and patterns, caused by a layer of tiny elastic pigment sacs just under the skin.
They are spectacular creatures to see while diving. In Tasmania, cuttlefish are found in caves and around rocky reef areas, in seagrass and in kelp forests.
