Conidae
Conidae, with the current common name of "cone snails", is a taxonomic family (previously subfamily) of predatory sea snails, marine gastropod molluscs in the superfamily Conoidea. The 2014 classification of the superfamily Conoidea groups only cone snails in the family Conidae. Some previous classifications grouped the cone snails in a subfamily, Coninae. As of March 2015 Conidae contained over 800 recognized species. Working in 18th-century Europe, Carl Linnaeus knew of only 30 species that are still considered valid. The snails within this family are sophisticated predatory animals. They hunt and immobilize prey using a modified radular tooth along with a venom gland containing neurotoxins; the tooth is launched out of the snail's mouth in a harpoon-like action. Because all cone snails are venomous and capable of "stinging" humans, live ones should be handled with great care or preferably not at all. Current taxonomy In the Journal of Molluscan Studies, in 2014, Puillandre, Duda, Meyer, Olivera & Bouchet presented a new classification for the old genus Conus. Using 329 species, the authors carried out molecular phylogenetic analyses. The results suggested that the authors should place all living cone snails in a single family, Conidae, containing the following genera: Californiconus J. K. Tucker & Tenorio, 2009 Conasprella Thiele, 1929 † Conilithes Swainson, 1840 † Contraconus Olsson & Harbison, 1953 Conus Linnaeus, 1758 † Eoconus J. K. Tucker & Tenorio, 2009 † Hemiconus Cossmann, 1889 † Herndliconus Petuch & Drolshagen, 2015 Kenyonia Brazier, 1896 Lilliconus G. Raybaudi Massilia, 1994 Malagasyconus Monnier & Tenorio, 2015 † Papilliconus Tracey & Craig, 2017 Profundiconus Kuroda, 1956 Pseudolilliconus J. K. Tucker & Tenorio, 2009 Pygmaeconus Puillandre & Tenorio, 2017 † Tequestaconus Petuch & Drolshagen, 2015 † The authors grouped 85% of all known cone snail species under Conus. They recognized 57 subgenera within Conus, and 11 subgenera within the genus Conasprella. History of the taxonomy Overview Prior to 1993, the family Conidae contained only Conus species. In 1993 significant taxonomic changes were proposed by Taylor, et al.,: the family Conidae was redefined as several subfamilies. The subfamilies included many subfamilies that had previously been classified in the family Turridae, and the Conus species were moved to the subfamily Coninae. In further taxonomic changes that took place in 2009 and 2011, based upon molecular phylogeny (see below), the subfamilies that were previously in the family Turridae were elevated to the status of families in their own right. This left the family Conidae once again containing only those species that were traditionally placed in that family: the cone snail species. 1993, Taylor et al., Bouchet & Rocroi According to Taylor, et al. (1993), and the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, this family consisted of seven subfamilies. Coninae Fleming, 1822 — synonyms: Conulinae Rafinesque, 1815 (inv.); Textiliinae da Motta, 1995 (n.a.) Clathurellinae H. Adams & A. Adams, 1858 — synonyms: Defranciinae Gray, 1853 (inv.); Borsoniinae A. Bellardi, 1875; Pseudotominae A. Bellardi, 1888; Diptychomitrinae L. Bellardi, 1888; Mitrolumnidae Sacco, 1904; Mitromorphinae Casey, 1904; Lorinae Thiele, 1925 Conorbiinae
