The other big yellow one, with heavier black markings and a rougher back.
A large, rigid dorid to about 12 cm, deep yellow to orange-yellow with irregular black markings that are broader and more broken than the fine lines of Notodoris minor, and with a back that carries low ridges and swellings rather than being smooth. The rhinophores are stout and the gill is small for the size of the animal. The two species overlap and are regularly confused; the black on minor runs as thin longitudinal lines, the black here as blotches and thick bars.
Feeds on calcareous sponges of the genus Leucetta, which are themselves bright yellow, and is very often found sitting directly on one — the sponge is the search image, not the slug. Egg ribbons are laid on or beside it. Recorded from about 5 to 30 m. Like its congener it is firm-bodied and slow, so the practical problem is lighting a large saturated yellow subject without losing the black pattern in the highlights.
Ratings are per location: 1 means found on most dives that look for it, 5 means a handful of records. Where enough dives have been logged the figure is calculated from them; otherwise it is an editorial estimate, and says so. We publish habitat and destination, not the dive site.
