Prickly Snail - Acanthinula aculeata


Though tiny (around 2mm), this snail is distinctive with regular spines along the centre of each whorl and ribs radiating from each spine. Whilst the spines can wear off the ribs remain. It also has a circular mouth.

The spines tend to collect soil and organic debris making this snail harder to detect.

Identification difficulty

Typically found in woodland and hedgerow leaf-litter but also under stones and logs.

When to see it

All year.
