Dear Bill,

Dear Koh,
Favorinus tsuruganus appears to eat a wide variety of opisthobranch eggs. The photo alongside shows the structure of the rhinophore of this species very well. It also shows a large pink lump on the back of the Favorinus. I guess this is a crustacean parasite, perhaps a copepod. In total these photos show a trophic chain running from compound ascidian > Goniodoris > Goniodoris eggs > Favorinus > crustacean parasite.
Best wishes,
Bill Rudman
