» Life History
Round rocksnails are gill breathing snails that are found attached to cobble, gravel, or other hard substrates in the strong currents of riffles and shoals. Since this snail is not very mobile and is not thought to migrate within the stream, it is thought that females live and attach their eggs to the same habitat (Goodrich 1922).
Similar to the painted rocksnail, round rocksnails will lay their eggs in concentric rings, usually with one or two central eggs, at temperatures between 14-27 degrees C (Whelan et al. 2015).
