Allognathus
Allognathus is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Helicidae, the true snails. The genus is endemic to the Balearic Islands (Western Mediterranean) being present in all major islands and in several small islets.[2] The genus colonized the archipelago from the south-eastern Iberian Peninsula during the Middle Miocene, throughout a land-bridge connection. The different species belonging to Allognathus live in crevice rocks or under stones.

gollark: I should really look into signed GPS responses somehow.
gollark: Yes, this is good as they can be detected from across the overworld.
gollark: I don't remember this happening. But I PRed in anonymization a while back.
gollark: Well, if they don't move it's fine, but the IDs were removed some time back.
gollark: If you want to do something actually usefulish, "FORTRESS", you can trilaterate GPS pings and find anyone who sends them (but not actually uniquely identify them since a few versions back).
