Snail Detectives Wanted!

By Ruth D'Alessandro, The Wildlife Gardener

It’s not often The Wildlife Gardener finds something that neither she nor The Ranger can identify. So we are sending out an NOS (Name Our Snail) request to Naturenet readers. While out walking near a mill pond I spotted several of these snails crawling all over cow parsley:

What on earth is it?

They are very different from the usual Grove snails (Cepaea nemoralis) found on chalk downland:

Grove snails (Cepaea nemoralis)

The largest of these unusual snails was about 2.5cms, the one pictured about 1 cm. At first glance I thought they were pond snails far from home (relatively), but those have triangular fleshy horns peeping out from under the shell. The heads and bodies of the mystery snails are very much those of a terrestrial snail.

The nearest matching snail I could find on Google was a Galapagos land snail. If so, they are a bit lost. Perhaps a couple of them fell out of Charles Darwin’s pocket in nearby Downe, and descendants arrived here in Surrey 170 years later.

The Ranger, no snail expert, suggested tentatively Cochlicopa species, although I think they have too much of a 'turret'.

So, we are very intrigued to find out what they are. An undiscovered species? Helix naturenetii? Readers, can you help us?

See follow-up for a very well-informed answer!

You should have sent one to "Janet Ridout Sharpe, a snail expert based in Oxford" like the National Trust volunteer at Cliveden. It might be another new species!

Thank you for this, David. I've found an email address for Janet and sent her a picture, so watch this space. How exciting if it is a rare or new species!

I don't think I've ever learnt so much about snails in my entire life! What great post - made me smile.

Keep watching this space, Frank. There's more snail fun to come!

The thoughts and writings of The Virtual Ranger, since 1995 the host and mascot of Naturenet, the UK's most popular independent environmental website; along with interjections from his real-life alter ego, Matthew Chatfield, and others. Featuring not only Naturenet and countryside related stuff, but, as on Naturenet, plenty of other material - more or less at random - that takes The Ranger's fancy. But you can be confident that soon enough he'll be rather sarcastic.
