Description
Pharaoh cuttlefish (Sepia pharaonis) pair showing the mottled colours that camouflage them against the reef. These invertebrate animals are marine molluscs that have well-developed senses and a large brain. An internal shell (the cuttlebone) provides buoyancy. Cuttlefish move by jet propulsion. When alarmed they will emit an inky fluid. Their skin colour can vary rapidly in response to danger and when mating. The eight arms and two tentacles are used to feed, mainly on crustaceans. These cuttlefish are fast-growing inhabitants of warm waters, and can reach around 45 centimetres in length. Photographed at Richelieu Rock, near Thailand, in the Andaman Sea.
