» Life History
Rough hornsnails are primarily found on gravel, cobble, and bedrock in moderate currents. They have been collected at depths of 1 m (3.3 ft) to 3 m (9.8 ft) (Hartfield 2004, p. 132). The species appears to tolerate low-to moderate levels of silt deposition (Sides 2005, p. 127).
Snails in the genus Pleurocera generally lay their eggs in a spiral arrangement on smooth surfaces (Sides 2005, pp. 26–27), whereas Elimia snails generally lay eggs in short strings (P. Johnson 2006). Attempts to induce rough hornsnails to lay eggs in captivity have been unsuccessful (Sides 2005, p. 27).
