Cylindrobulla
Introduction '''''Cylindrobulla''''' is a genus of sea snails or bubble snails, marine gastropod mollusks in the clade Sacoglossa. ''Cylindrobulla'' is the type genus of the family '''Cylindrobullidae''' and it is the only genus in the family.
Taxonomy The suborder '''Cylindrobulloidea''' used to be recognized as monogeneric suborder; in other words there was only one family in the suborder, the family Cylindrobullidae, and only one genus ''Cylindrobulla''.=== 1996 taxonomy ===It was treated by Jensen (1996) as a sister group of Sacoglossa and placed it in the new order Cylindrobullacea.=== 1998 taxonomy ===Mikkelsen (1998) has argued that the genus ''Cylindrobulla'' actually belongs in Oxynoacea within shelled Sacoglossa. This change in taxonomy was suggested on the basis of the similarity in many characteristics: digestive, sexual, pallial (= concerning the mantle), and the nervous system.=== 2005 taxonomy ===According to the taxonomy by Bouchet & Rocroi (2005), is the '''Cylindrobullidae''' the only family in the superfamily '''Cylindrobulloidea''' and Cylindrobulloidea is the only superfamily within the group '''Cylindrobullida''' in the informal group Opisthobranchia.According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Cylindrobullidae has no subfamilies.=== 2010 taxonomy ===Molecular phylogeny analysis by Maeda et al. (2010) have confirmed placement of ''Cylindrobulla'' within Sacoglossa.
