Blue Dragon nudibranch laying eggs

Pteraeolidia ianthina

Description:

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!
