Identification:  This species has a very small, transparent-white shell with an angled umbilicus. Live animals are black, spotted with chrome-yellow (usually in a "butterfly" pattern). Sometimes, the background within the "butterfly" may be lighter with dark blotches. Natural history:  Shells of Rissoella cf. confusa are moderately rare in beach drift. However, live animals are common on reef flats and in tide pools at moderately protected to moderately exposed sites. They also occasionally occur in large numbers on sand in shallow basins. (Note 1) Distribution:  Maui, Oahu, Kauai and Midway: Rissoella confusa is widely distributed in the western and central Pacific. Taxonomic notes: Shells are similar to those of  R. confusa found in Japan. (Kay, 1979) Photo:  Invert Team: 2017 MarineGeo; Kaneohe Bay, Oahu; May 30, 2017. Observations and comments: Note 1:  Dozens are often found in single algae washes and hundreds in skimmed sand samples (if there's a bloom).
