resembles Rissoina plicatula,but not totally the same,dead collected on shore
Empty shell found while scanning the high driftline. Not sure if it’s the same species with the one from East Sea(I found several P. nobilis from Gosong). : https://www.inaturalist.org/observations/148777020
Ones from West Sea or Yellow Sea seem to have more fine and less developed radial ribs.
Quite rare to find on beaches

Quite rare to find on beaches, this one is the best one I’ve ever find from this area.
