Identification: This species has a strongly inflated brown shell spotted with white and streaked with darker brown. The animal is cream frosted with brown and variably flecked with white. It may be distinguished from Bulla peasiana by its more strongly inflated and heavily calcified shell as well as by the smaller translucent areas around the eye spots. Natural history:  Bulla vernicosa is a moderately common species found in protected to moderately exposed mixed habitats and in Halimeda kanaloana beds at depths of < 1 to 15 m (< 3 to 49 ft). Dredged shells from the Bishop Museum extend the depth range to at least 183 m (600 ft). It is nocturnal, burying itself in sand or concealing itself under rocks during the day. It feeds on the green algae Enteromorpha and lays an egg mass composed of tangled, yellow strings (Kay, 1979). On Oct. 22, 1994 a tiny, orange commensal copepod was found on a large animal from Airport Beach, Maui. Distribution:  Big Island, Maui and Oahu: widely distributed in the western & central Pacific. Taxonomic notes:  The photo labeled Bulla vernicosa in Kay, 1979 is actually Bulla peasiana (Kay considered that species a synonym of B. vernicosa at the time).
