Austrolittorina unifasciata (syn. Nodilittorina unifasciata)

Field Notes
Description:
These small sea snails are about the size of your little fingernail and are the most abundant molluscs on the rocky shore, generally found toward the high-tide mark. They were all over the place in small clusters, particularly around the calmer rock pools. This species is the only one of its genus found in Australia. I was really surprised to see how pitted and warn the shells were. An indication of age perhaps?
Habitat:
Ocean rock pools at North Avoca Beach. Beautifully crystal-clear seawater on the now receding tide.
