Where
seen? This very large nudibranch with whorls of bumps on the upper side
and a spotted underside is sometimes seen on some of our Southern
shores, near reefs and seagrasses. It may be seasonal: when seen,
often many individuals are spotted during the same trip.
Features: 12-15cm long. The upperside
with lots of conical bumps arranged in clusters so that that resembles
a cauliflower. Colours from dark greyish blue, pinkish purple to pale pink. The underside is distinctive with large pale round spots on a plain smooth background, usually darker. Large rhinophores and large feathery
gills. |
