Description Up to 2 cm long, mottled in shades of green with a few flecks of white and brown. Almost invisible, but probably quite common when one knows what to look for. Habitat: supralittoral fringe on extremely exposed rock faces. Animals are kept moist by the splash of the surf and abundant mucus production; one of the very few opisthobranchs which can live in a habitat not permanently covered by the sea. Distribution: Indo-Pacific. [details]
