Info
Goniobranchus obsoletus (Rüppell & Leuckart, 1830)
Goniobranchus obsoletus is a chromodorid nudibranch with a mostly white mantle and an orange mantle edge. There is an irregular band of blue-black just inside the orange margin and the mantle is rugose with an orange-brown reticulation between the raised pustules. The rhinophores and gills are translucent brown with white markings.
This species prey on a dark purple-brown sponge on which they are sitting. I am pretty sure this sponge is the aplysillid Chelonaplysilla violacea, or at least a close relative.
