***Gyraulus*** is a [genus](/source/Genus) of small, mostly air-breathing, [freshwater snails](/source/Freshwater_snail), [aquatic](/source/Aquatic_animal) [pulmonate](/source/Pulmonate) [gastropod](/source/Gastropod) [mollusks](/source/Mollusk) in the family Planorbidae, the [ram](/source/Sheep)'s horn snails.[2]

The genus *Gyraulus* is known from the Early [Cretaceous](/source/Cretaceous) to the present. Fossils attributed to *Gyraulus* sp. have been found in the lakebottom sediments of the [Yixian Formation](/source/Yixian_Formation) in China, dating to 125 million years ago.[3]

## Description

Shells of the species within this genus are small, and are mostly almost planispiral in their coiling.

## Distribution and habitat

The distribution of this genus is [Holarctic](/source/Holarctic). These snails live on water plants in freshwater.
