Anyway, presumably the snail has to use growth hormones to regrow the eye stalk, some defect on the stump may cause the hormone to separate into two and both grow eyes. Only a theory...

It's a Cepaea Nemoralis, aka. the Brown Lipped Snail, aka. the Grove Snail.

thegreatloofa, it's a good theory but in animals, hormones are created rather than being located in plants like giberellins are. If you top a plant it can split into 2 shoots, if you lopped a lizard's tail off it would grow back normally.
Actually, did anyone ever see that New Scientist article about regeneration of limbs in mice and other mammals? They turned the mice's immune system off and the mice grew ears, tails and even full legs back. Our immune system retards regeneration.

Ah, okay then. I was going off those frogs in America somewhere that had multiple limbs and whatnot. They got them because a parasite attacked the base of the limbs when they were forming and in some cases caused mutations not unlike this three-eyed snail. I was suggesting during the regrowth process something along similar lines was happening to this snail, but I don't have all the information on these frogs to draw too many parallels. Also, I have a yukka in the same room as me and the idea just popped into my head ;D

Well, you're right in that respect. It could well be the case that the snail lost its eye and something caused the mutation at the point of severance.

snails have poor vision. they can make out the difference between light and dark but thats about it. they rely more on their feelers and sense of smell. helix pomatia can smell something 30cm away. some snails accidentally lose feelers in the wild, due to predators or accidents.
kind regards

Taken from: www.rainbowsnails.com/Forked Tentacles / Forked Siphon Forked tentacles occur during periods of growth, usually caused by cysts (see above). They are nothing to worry about, and if nipped off by a fish they will grow back normally. Forked siphons are also not a major problem, but a snail with a branching siphon may require more space above the waterline to breath. The cause of forked siphons is unknown, but they appear to be inherited in some cases.
