Sea Lemon

Sea Lemon

Observation - Sea Lemon. Description: About 2.5cms. Seemed like a sponge at first encounter.

About 2.5cms. Seemed like a sponge at first encounter. But close photo-inspection reveals two 'antennae' and feathered gills.
I established it as a Discodorididae, thinking it might be Jorunna tomentosa on the grounds of size and the nearby egg ribbon (broken but shown - picture 3)
But was not able to discount the more common Sea Lemon as it has a quite blotchy appearance and the antennae do not appear to be stalked.

There is still a fair chance it might be Jorunna tomentosa
