Nudibranch (16-20Jun10) 02.jpg
Green Island, Taiwan -- Nembrotha milleri of the Polyceridae family.
This nudibranch is easily recognizable by its greenish-black color with black pigment on the rhinophores and gills. Its body tissue is relatively smooth with longitudinal folds.
It feeds on solitary or colonial tunicates (sea squirts) and is usually found at a relatively shallow depth of 3-10 m.
Members of Nembrothinae have relatively small oral tentacles compared to other members of the polyceridae family, e.g. Roboastra luteolineata elsewhere in this gallery.
