Although I didn’t think to put something down beside the creature as a measure, it was around the size of my little finger.
Later when I went back with a measure the slug was gone but a slime-print remained. That print was around 6 cm long.
The slug was dining on a fragment of mushroom that had grown beneath a bag of pea-straw. It had amazing eye-stalks that it withdrew shortly after I’d taken the photo. Perhaps the flash on my camera frightened or blinded it.
I know nothing about slugs, but is that perhaps an ear further back on its head? [Later: Oh, Wikipedia reveals that it’s a pneumostome — a respiratory opening. ]
