Cuttlefish at Fairy Bower

Biodiversity #21 – The Cuttlefish

Despite the name, the cuttlefish is not a fish, but a cephalopod (literally: ‘head-foot’) which includes close cousins squid and octopus and distant cousin: the Nautilus. Unique internal shell called a cuttlebone which, being porous it can use to regulate buoyancy. (In-built BCD!)
