''Nataliconus'' is a proposed genus of sea snails, marine gastropod mollusks in the family Conidae, the cone snails and their allies.〔Bouchet, P. (2011). ''Nataliconus'' Tucker & Tenorio, 2009. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=574472 on 2012-01-21〕 This genus currently (November 2011) is still treated by some experts as an "alternative representation" of this group of species. When the "alternative representations" are not used, this group of species is instead still placed in the Linnaean genus ''Conus''. ==Distinguishing characteristics== The Tucker & Tenorio 2009 taxonomy distinguishes ''Nataliconus'' 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.〔 * Genus ''Nataliconus'' Tucker & Tenorio, 2009 ::Shell characters (living and fossil species) :::The shell is conical to cylindrical in shape with a conic spire and angular to subangulate shoulders. The protoconch is paucispiral. The whorl tops have an enlarged ridge in the center and cords which may die out early or become numerous and small. Nodules are either absent or die out very early. The anal notch is deep. The body whorl is fairly smooth and is ornamented with spiral lines of minute tents, but textile bars are absent. ::Radular tooth (not known for fossil species) :::The anterior section of the radular tooth is greatly elongated in comparison with the posterior section. A basal spur is absent, and the barb and blade are short. The waist is not obvious, and the radular tooth has serrations and a terminating cusp. ::Geographical distribution :::These species are endemic to the South African region. ::Feeding habits :::These species are molluscivorus, meaning that these cone snails prey on other mollusks. These cone snails have been shown to have a preference in prey, and choose to eat mollusks in the family Ranellidae.〔〔S. Veldsman (1999) ''Three cones from Transkei, South Africa.''
