Olive snails, also known as olive shells and olives, scientific name Olividae, are a taxonomic family of medium to large predatory sea snails with smooth, shiny, elongated oval-shaped shells. 〔 Bouchet, P.; Gofas, S. (2012). Olividae. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=23082 on 2012-06-11 〕 The shells often show various muted but attractive colors, and may be patterned also. They are marine gastropod molluscs in the family Olividae within the main clade Neogastropoda. Also see the Olivellidae, the dwarf olives, which were previously grouped within this family, but which now have their own family. ==Taxonomy== According to the taxonomy of the Gastropoda by Bouchet & Rocroi (2005) the family Olividae consists of three subfamilies: * Olivinae Latreille, 1825 - synonyms: Dactylidae H. Adams & A. Adams, 1853 (inv.); Agaroniinae Olsson, 1956; Olivancillariidae Golikov & Starobogatov, 1975 * Ancillariinae Swainson, 1840 - synonym: Ancillinae H. Adams & A. Adams, 1853 * † Vanpalmeriinae Adegoke, 1970 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Olive snail」の詳細全文を読む スポンサード リンク
