A cuttlefish hovers in the middle of reef "vegetation" (most of which is actually colony animals). From top clockwise are brown, red, and bright green crinoids. In the bottom left is a branching hard coral. The cuttlefish is roughly lozenge shaped, with a curtain of ten tentacles hanging down from its eyes. Its colouration is mainly red brown, with brilliant blue dots around the equator of the lozenge.
