Cremnoconchus

Cremnoconchus is a genus of small freshwater snails, gastropod mollusks in the (mostly marine) family Littorinidae, the winkles or periwinkles.

The generic name Cremnoconchus is from the Greek word κρημνός which means precipice and from the Ancient Greek word κόγχος which means shell.

This genus is the only freshwater genus within the Littorinidae; all other Littorinidae are marine. Two Cremnoconchus species live in waterfalls.
