Uh-oh... I have heard that New Zealand hydrobiid Potamopyrgus
antipodarum is clogging streams in the Pacific Northwest. This limpet
sounds suspiciously like another Kiwi, Notoacmea pileopsis (Q&G
1834), which is characterized by a spiral ("radial") white band which
forms an acute V; it reaches about 1.4cm and lives on or under
intertidal rocks and on other shells.
