Spotted hypselodoris
Philippines · Indo Pacific - South China Sea
A small chromodorid nudibranch, uncommon across its wide Indo-Pacific range. It is easily confused with Hypselodoris decorata, and reliable separation of the two may require molecular data.

Pale cream to pinkish body with several (about 4–6) thin opaque white longitudinal lines and purplish-red spots between them. The undulating mantle margin is orange-brown to red-purple with white spots. Rhinophores are white with red rings on the club; the white gills have purplish-red spots at the base and vermilion tips.
Hypselodoris decorata is very similar; rhinophore ring counts overlap, so the two may not be separable from photos alone.
Reef edges and reef flats, from the intertidal to about 18 m.
Sponges, reportedly Euryspongia.
