Distribution

This species was first described from Devon. It has subsequently been reported widely in Britain and Ireland where it is common from the lower shore to moderate depths.[5]

Description

This goniodorid nudibranch is translucent white in colour, with spots of white and yellow.[6] It can reach 27mm in length. Its mantle is reduced and shows its foot.[7]

Ecology

Goniodoris nodosa feeds on bryozoans of the genus Alcyonidium, including Alcyonidium diaphanum, and, when fully grown, the tunicate Dendrodoa grossularia and Botryllus schlosseri, family Styelidae.[7]

gollark: `Wants: free to first hatchling offer ` ← WHY, trade hub user, WHY?
gollark: That looks quite good.
gollark: Horribly late to this party, but I really like the new dragons and probably should have tried to catch them during the release.
gollark: I wonder if I could just submit an egg shaped bit of static and call it a glitch egg.
gollark: Or you can list multiple wants and find the best offer!
