Masters of Living Color

Cuttlefish are cephalopods, relatives of squid and octopuses. Their skin holds chromatophores, tiny pigment sacs that muscles stretch open, along with reflective cells. Controlled by nerves, they can change color and pattern in under a second.

They have W-shaped pupils, three hearts and blue blood. An internal cuttlebone helps control buoyancy, and washed-up cuttlebones are given to pet birds. Their ink gave its name to the color sepia. In a passing cloud display, dark bands ripple across the skin, perhaps to startle prey.

Some small males disguise themselves as females to slip past larger rivals. Each winter, thousands of giant cuttlefish gather to breed in shallow waters of South Australia, a famous diving spectacle.
