Description
Jorunna (Bergh, 1876) is an accepted genus of dorid nudibranchs in the family Discodorididae. Its species are usually camouflaged to match the sponges they feed on, especially sponges of the family Chalinidae, and the genus occurs in most warm and temperate seas. Colour varies widely, from plain cream to the spotted Jorunna funebris and the pale pink Jorunna parva.
Identification
The back is velvety, densely covered with caryophyllidia (minute stalked papillae ringed with spicules and tipped with a sensory knob), giving a felt-like look. Colour is not a reliable guide to relationships within the genus.
