I thought I had ‘done’ snails, but on the back of the old wooden bridge that was lying against the drystone wall of the ramp, I realised that this little brown snail was unlike the others as its shell was flattened like a disc. The shell was brown and flat with dense ribbing and darker patches. The body of the snail was blue-black on top with paler grey underneath. The disc snail eats plant debris, fungi ad algae. They live in moist sheltered places, like leaf litter, dead logs and under stones.
