Cuttlefish are small relatives of squids and nautilus, sometimes called the chameleon of the sea because of their remarkable ability to rapidly alter their skin color at will. They have an internal shell, large eyes, and eight arms and two tentacles furnished with denticulated suckers, by means of which they secure their prey. There are 119 species of cuttlefish.
