Gyraulus is a genus of small, mostly air-breathing, freshwater snails, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails. [2]

Contents

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

The minute species Gyraulus crista , although technically a pulmonate gastropod, does not use air for respiration, but instead has a mantle cavity which has much water.

Distribution

The distribution of this genus is Holarctic.

Habitat

These snail snails live on water plants in freshwater.

Shell description

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