These guys are the real beauties of the cuttlefish world. They're normally rather drab looking and blend in well with the black sand bottom. However, when excited or frightened, they flash brilliant patterns and colors in shades of yellow, purple, and white. This is a large adult cuttlefish. The smaller younger cuttlefish of this species have even more striking coloration.
