Each snail measures roughly the width of a fingernail and carries a small, cone-shaped shell built for a life spent wedged into narrow cracks in the rock. Rather than a simple flap, each one has a round disk on its tail that functions like a tiny door, sealing the shell shut the instant the animal withdraws inside. One of the two species survives only within a single narrow canyon that a planned dam could submerge before researchers finish cataloguing whatever else lives there, unseen, on the same cliffs.

The team named the two snails after the very places where they were found: one after the canyon itself, the other aft...

The team named the two snails after the very places where they were found: one after the canyon itself, the other after a nearby high plateau. Researchers note that the discovery shows how, even in well-mapped corners of Europe, whole species can still be waiting, unnamed, on a single cliff face.
