really would appreciate some help on a Nudi-ID. I photographed this Thecacera Nudibranch last week and have no idea what it is. Firsat i was thinking it could be a Thecacera picta variation with just the orange/red parts missing. But then i realised, that first the black lines go all the way through and don't form the typical dots like on the side of the pica, second the red is completely non-existant and third the "ears" of the Nudi are very pointed and not rounded like on the picta.
Photographed in Lembeh Strait in about 15m depth on a sandy patch.
Anyone has an Idea?
