Nassarius oneratus (Deshayes, 1863)

Nassarius oneratus seems to prefer relatively shallow water on both eastern and western seaward reefs, but can also be found on some lagoon pinnacles. On the seaward reef, it often lives buried under thin layers of sand over hard reef up on the flat in shallow water. On the intertidal, reasonably fresh-looking shells inhabited by hermit crabs are common in some places, but we have not seen living animals in those areas. It is possible that shells living on the shallow seaward reefs are regularly tossed up on the reefs, where they are taken over by hermits. Maximum size we have seen is 15.2mm.
