This nudibranch can have a thicker body (above) or a very fine and nearly transparent look (below). This beautiful nudibranch eats mostly algeas.
I found it together with a yellow frogfish, two ghostpipefish and several scorpionfish on a large rotten tree trunk on the sand on Ankermi House Reef in Flores.
