Conilithidae is a proposed taxonomic family of small to medium-sized sea snails, specifically cone snails, marine gastropod mollusks in the superfamily Conoidea, the cone snails and their allies.
In 2009, John K. Tucker and Manuel J. Tenorio proposed elevating the subfamily Conilithinae (previously placed in the family Conidae) to the rank of family. This was based on a cladistic analysis of anatomical characters, including the radular tooth, the morphology (i.e. shell characters), as well as an analysis of prior molecular phylogeny studies, all of which were used to construct phylogenetic trees. In their phylogeny, Tucker and Tenorio noted the close relationship of the various species within the genera in the Conilithidae; this also corresponded to the results of prior molecular studies by Puillandre et al.. Tucker and Tenorio’s proposed classification system for the cone shells and their allies (and the other clades of Conoidean gastropods) is set forth at Tucker & Tenorio cone snail taxonomy 2009.
Like other species in the superfamily Conoidea, these snails are predatory and venomous, able to inject neurotoxins into their prey with their radula. The species in this family are capable of "stinging" humans, therefore live ones should be handled carefully or not at all.
Proposed genera within the Conilithidae include:
Prior to 2009, all cone species were placed within the family Conidae and were placed in one genus, Conus. In 2009 however, J.K. Tucker and M.J. Tenorio proposed a classification system for the over 600 recognized species that were in the family. Their classification proposed 3 distinct families and 82 genera for the living species of cone snails, including the family Conilithidae. This classification was based upon shell morphology, radular differences, anatomy, physiology, cladistics, with comparisons to molecular (DNA) studies. Recent published accounts of the family Conilithidae and its genera include J.K. Tucker & M.J. Tenorio (2009), Tucker & Stahlschmidt (2010), Tucker, Tenorio & Stahlschmidt (2011), Bouchet et al. (2011), Puillandre et al. (2011), Tucker & Tenorio (2011), Petuch & Sargent (2011), and Petuch & Drolshage (2011).
