Many of these Marionia were seen on or around Xenia soft corals near Padangbai in October 2017 and November 2022. They may overlap with Marionia sp. b318.
This one has an interesting growth on his right rhinophore.
Those below are from 2022.
With a smaller specimen of the one we are calling Marionia sp. b319 and what appears to be the egg mass of a pleurobranch.
The one below is likely something different.
