Cylindrobullidae
The family Cylindrobullidae (listed in some sources as Volvatellidae) includes small species with thin, lightly calcified shells that have constricted apertures. Most are associated with green algae of the genus Caulerpa. However, the genus Cylindrobulla burrows in sand and feeds on Halimeda. They often emit a whitish defensive chemical when disturbed. At least four species have been recorded from Hawaii in two genera (Cylindrobulla and Volvatella). Some authors place the genus Cylindrobulla in its own order, the Cylindrobullida.
