Description

Onchidella celtica is up to 12mm long and its oval body has a deep olive to black colour. The mantle is covered with large tubercles which concealed the head and the foot of the animal when motionless. The eyes are at the tips of two short and thick tentacles and are visible from above when the animal is crawling.[4]

Distribution

This species occurs locally on the East Atlantic coastline, from western Scotland, western England and the Channel Islands, south to Spain and the Azores, including:

Habitat

This air-breathing sea slug lives in the intertidal zone on rocky shorelines. It is exposed on rocky shores at low tides and retreats to crevices when the tide rises.[4]

gollark: I feel like laws being hundreds of pages of legalese is quite a big problem, as it means no human can actually fully know all the law they're legally bound by.
gollark: It seems to be a law or something talking about editing another law in an overly precise way.
gollark: For *most* things you need more than one.
gollark: I mean, 3D printing exists and all, but it's not efficient compared to... whatever else is done to make plastic things in bulk.
