PHOTO
Darwin, Northern Territory, Australia, November 1985, 75mm long alive. PHOTOS: Bill Rudman.
Ceratosoma palliolatum lacks the prominent dorsal horn found in species such as C. trilobatum, but the body is relatively high and firm to touch. The gills are characteristically long with few lamellae. Thye are almost invisible in the accompanying photos because their colour matches the colour of the mantle. The rhinophores are tipped in purple. The body is a mottled orange with scattered purple spots around the mantle edge.
