This small snail is found in seagrass and algae beds. Its conical shell is an iridescent green, either with or without a striped pattern that can be quite variable. It is herbivorous, feeding on the microalgae that often grows on the larger plants. Its small size and/or iridescence distinguishes it from the many similar snails found in the state, including Austrolittorina unifasciata and Thalotia conica.
