Molluscs

Photo gallery of the Mollusca found in NG3963. From now on I shall make a concerted effort to obtain half-decent images for every species. I'll replace this initial collection of pictures with better ones as I take them and add new species as I encounter them. Updated 16th May 2017

Slugs
Arion flagellus (Green-soled Slug) 
By far the commonest large Arion up here so far
Arion ater (Black Slug)
Fringe lines penetrating into sole distinguish from black coloured A.flagellus
Arion circumspectus silvaticus (Silver False-keel Slug) 

Arion distinctus (Brown Soil Slug)
Arion hortensis EDIT: still to be confirmed, probably A.distinctus - would be new to Skye.
These two images are of the same individual
 Arion intermedius (Hedgehog Slug)

Boettgerilla pallens (Worm Slug)
Boettgerilla pallens - first discovered on Skye in the early 2000s
Deroceras invadens (Tramp Slug)
Deroceras invadens - a successful invasive alien in Britain
Deroceras reticulatum (Netted Field Slug) 
An extremely variable and common species in NG3963
Lehmannia marginata (Tree Slug)
Commonly found climbing tree trunks in wet weather

Cepaea hortensis - a typical patterning, note the pale lip
Clausilia bidentata (Two-toothed Door Snail)

 Lauria cylindracae (Common Chrysalis Snail) 
Lauria cylindracea with the larger (but still very small) Balea perversa

Freshwater Snails
Ancylus fluviatilis (River Limpet)

Clearly A LOT of these images are pretty crap! As stated at the top of the page, I intend to improve on these initial images and end up with a respectable gallery of the Mollusca of NG3963. Give it time...
