A small slug, roughly 5cm long. Crossing the path in a wooded park.
No interactions present.
I'll have to have a look and see if I can find another and confirm it. Out of interest, I'm having a little trouble seeing the v-shaped groove - is the 'point' of the v pointing towards the slugs head, or away from it?
Also, do you have a guide to UK slugs, as I've been wanting to get hold of one for a while but I don't know what's best.
The V isn't easy to see - it's a fine line with the point towards the head. On the first image, part of it is marked with darker marbling, but that isn't always the case.
I think the recommended guide is still the AIDGAP key:
Cameron, R.A.D., Eversham, B.C., & Jackson, N. 1984. A field guide to the slugs of the British Isles.
AIDGAP publ. no. 156, 23pp.
Just discovered: it's free to download from
but is listed under 1983. Click on the title or authors.
(Confession: I'm the middle author). It really needs updating or replacing: a couple of species are missing, and we could do better with large Arion and the A. hortensis grop now. I've got a manuscript key from the 1990s, but need to digitise it and put it on line... a job for the holidays perhaps!
If you're ever looking for books etc., there's a literature guide at
which we try to keep up to date.
