Pteraeolidia ianthina
This Pteraeolidia ianthina was spotted laying an egg ribbon on the operculum of another gastropod, which appeared to still be alive. Perhaps not the best location choice! Pteraeolidia has evolved a method of capturing and farming microscopic plants (zooxanthellae) in its own body. The plants flourish in this protected environment and as they convert the sun's energy into sugars, they pass a significant proportion on to the nudibranch for its own use.

Thanks Blogie! Probably not the smartest place to lay one's eggs though!
Astounding capture, Sam!
