''Globiconus'' is a subgenus of sea snails, marine gastropod mollusks in the genus ''Conasprella'', family Conidae, the cone snails and their allies. In the new classification of the family Conidae by Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015), ''Bathyconus'' has become a subgenus of ''Conasprella'': ''Conasprella (Fusiconus)'' Tucker & Tenorio, 2009 represented as ''Conasprella'' Thiele, 1929 〔 ( Puillandre N., Duda T.F., Meyer C., Olivera B.M. & Bouchet P. (2015). ''One, four or 100 genera? A new classification of the cone snails''. Journal of Molluscan Studies. 81: 1-23 ) 〕 ==Distinguishing characteristics== The Tucker & Tenorio 2009 taxonomy distinguishes ''Globiconus'' from ''Conus'' in the following ways:〔Tucker J.K. & Tenorio M.J. (2009), Systematic Classification of Recent and Fossil Conoidean Gastropods, ConchBooks, Hankenheim, Germany, 295 pp.〕 * Genus ''Conus'' ''sensu stricto'' Linnaeus, 1758 :: Shell characters (living and fossil species) :::The basic shell shape is conical to elongated conical, has a deep anal notch on the shoulder, a smooth periostracum and a small operculum. The shoulder of the shell is usually nodulose and the protoconch is usually multispiral. Markings often include the presence of tents except for black or white color variants, with the absence of spiral lines of minute tents and textile bars. ::Radular tooth (not known for fossil species) :::The radula has an elongated anterior section with serrations and a large exposed terminating cusp, a non-obvious waist, blade is either small or absent and has a short barb, and lacks a basal spur. ::Geographical distribution :::These species are found in the Indo-Pacific region. ::Feeding habits :::These species eat other gastropods including cones.〔 * Subgenus ''Globiconus'' Tucker & Tenorio, 2009 ::Shell characters (living and fossil species) :::The shell is cylindrical in shape. The protoconch is multispiral with 2.5 whorls. The anal notch is moderate to deep, and the anterior notch is absent. The whorl tops are smooth, and the early whorls are not nodulose but may be ornamented by an undulating carina. The body whorl is ornamented with grooves or sulci reaching the shoulder. The periostracum is smooth, and the operculum has not been observed. ::Radular tooth (not known for fossil species) :::The radular morphology of ''Globiconus'' is unique. The anterior sections of the radular tooth is roughly equal to the length of the posterior section, and the blade is short. A posterior fold is present and modified into a tube, and the posterior blade is absent. A basal spur is present, and the barb is short. A shaft fold is present and is blunt at its anterior end and not pronounced. ::Geographical distribution :::The only living species in this genus is occurs in the Eastern Pacific region. Fossil species in this genus have been found in the Eastern Pacific region. ::Feeding habits :::The only living species in this genus is vermivorous (meaning that these snails prey on marine worms).〔 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「Globiconus」の詳細全文を読む スポンサード リンク
