The purple ‘ribbons’ just behind the rhinophores are the external egg sacs of a parasite living internally inside the body of the nudibranch.

An undescribed species. The pink ‘sausage’ on the head of the Marionia is the egg sac of an internal copepod parasite (Crustacea: Copepoda: Harpacticoidea: Splachnotrophidae: Ismaila sp.). These parasites live permanently inside the body of nudibranchs and the only indication of their presence is their long and coiled egg sacs of the females that project outside the body. We have no idea what damage these parasites cause their nudibranch hosts.

Lovely, I think this may be a new species...

These are in a bit of a tangle at the moment.

This photo shows the distinctive red-spotted pattern on the side of the body and upper foot. However, because the photo does not show the back (which I assume is pustulose) or detail of the head, it is not possible to assign a species name to it.
