Sericominolia vernicosa (Gould, 1861)
8mm

These small active shells are very common to abundant on a range of lagoon, pinnacle and seaward reefs. By day they hide under rocks or in algae, and at night wander about on hard reef rock grazing. When disturbed, sometimes just by a dive light, they swim a short distance by twisting their foot rapidly like a propeller.
