Rostanga sp. 8 (in Nudibranchs and Sea Slugs Identification)

Talk about a master of disguise, this creature is amazing. Specimens are usually identical in color to the sponge they live on. Not sure if Ruben's critter here was moved. In any event specimens are almost invisible on the sponges they feed on (see page 200 in NSSI) for a good example. The complex network of lines on the dorsum of the nudibranch matches the spicules in the sponge's surface, providing its camouflage.

Specimens may reach about 20mm in length. Nice find Ruben!
