Identification:  This species has a thin, strongly inflated, cream shell marked with wide spiral brown bands. The body is cream grading to maroon marginally with a white marginal band. Natural history:  Although Hydatina zonata is typically considered to be a rare species found in sand at depths of 30-60 m (100-197 ft), the live Maui animal was found at a depth of less than 3 m (10 ft). Distribution:  Maui, Oahu and Kauai. Taxonomic notes:  This species is listed in Kay, 1979, Edmondson, 1946, Quirk & Wolfe, 1974, Morris, 1974 and Tinker, 1958 as Hydatina albocincta (Quoy & Gaimard, 1825) which is probably a synonym (see discussion on the Sea Slug Forum).
