Robust Lancetooth Snail

Garden snails eat plants. Right?

Not always…

There is one in our nature habitat/ garden that is a carnivore. Can you believe that? I was very surprised to learn about the Robust Lancetooth Snail (Haplotrema vancouverense).

This snail feasts on other snails. The name Lancetooth is inspired by the calcium carbonate spike they use to stab another snail. Once the other creature is punctured, the Robust Lancetooth follows the slimy trail. After its victim dies, the Lancetooth devours it. The same technique is also applied to small slugs and earthworms. Quite fascinating. It is appealing to think that this little snail could help keep the slugs at bay… without the use of chemicals!

Moral of the story: not all garden snails are pests. Some might be helpful.
