This one also looks like Phyllodesmium poindimiei. The picture was taken in Horseshoe Bay (between the islands of Rinca and Nusa Kode), Nusa Tenggara, Indonesia. The name of the divesite is Torpedo.

Depth: ~ 8 m
Size: ~ 4 cm

It was moving across a patch of black sand

Thanks Sabine,
Your animal certainly looks like P. poindimiei. My only doubt is that I can't see any branching on the pink digestive gland ducts which run up each of the cerata. I this genus there is quite a range of structure in the digestive gland duct, ranging from species with a smooth unbranched tube to others with major branches and tertiary ramifications throughout the cerata. If you look at other photos of P. poindimiei on this page you will see that there are quite noticeable secondary branches. I am not sure in your animal whetjher it lacks these or whether they are obscured by the pigment on the ceratal wall.
Best wishes,
Bill Rudman
