These are pale blue or white on top, sometimes sky blue underneath, and when removed from the animal they each resemble a butterfly giving the common name. The girdle is fleshy and smooth with short sutural bristles that protrude from 18 rounded pores, which are elevated and run in two crested rows from head to tail. The colour of the dorsal surface can range from dark brown to bright orange, while the underside of the girdle is pale orange with a bright orange foot.[6]
