Thickshell pondsnail

Ladislavella utahensis, common name the thickshell pondsnail, is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusc in the family Lymnaeidae, the pond snails.

The last whorl is inflated, with numerous rather marked transverse costae and minutely wrinkled.

[4] The aperture is elongately ovate, effuse, approaching patulous and pearly white within.

The outer lip is simple and its margin is connected by a slight calcareous deposit.

[5] This species was associated with abundant individuals of the snails Valvata utahensis and Fluminicola fusca and with the bivalve Sphaerium dentatum.
