Onchidella celtica from Channel Ids
February 11, 2002
From: Nick Jouault
I have seen what I think is Onchidella celtica over the the last two weeks of July at Bigorne, Les Ecrehous, Jersey, Channel Islands. Is it Onchidella celtica, and is the other picture its spawn. Any info on this would be appreciated.

Yes I think this is Onchidella celtica. Although marine, and a 'slug' it is not an opisthobranch sea slug, but rather a pulmonate land slug, closely related to most land snails. I have a page on this group as they are quite often asked about. Concerning your second photo. I am pretty sure the egg mass of Onchidella celtica will be fairly typical of the group, consisting of a jelly-like ribbon with a string of tiny eggs embedded in it. The objects in your photos look like a group of isopod crustacea.
Best wishes,
Bill Rudman.
