Simillar to Primnoidea CA10 but more branched and fluffy.
Shape like Hippasteria (https://www.inaturalist.org/guide_taxa/709479) but with no visible bumps. Colour and texture like Goniasteridae (https://www.inaturalist.org/guide_taxa/709487). I think Goniasteridae
What are the long slender white bits? Sea star arms? Anemone tentacles?
