Conorbidae

Conorbidae is a monophyletic family of small to medium-sized sea snails, marine gastropod molluscs in the superfamily Conoidea. Despite the name of the family, which might seem to suggest otherwise, this group of gastropods are not cone snails, but are instead what used to be loosely called "turrids".

==Taxonomy== In 2009, John K. Tucker and Manuel J. Tenorio elevated the subfamily Conorbiinae (at that point it was placed in the family Conidae) to the rank of family. This was based on a cladistical analysis of anatomical characters including the radular tooth, morphology (i.e. shell characters), as well as an analysis of prior molecular phylogeny studies, all of which was used to construct phylogenetic trees. Tucker and Tenorio noted a close relationship to genera such as Bathytoma in their phylogeny, which corresponded to prior molecular studies by Puillandre et al.. Shortly thereafter, in 2011, Bouchet, Kantor et al. confirmed the elevation of the subfamily Conorbiinae to the rank of family based upon a detailed molecular phylogeny of a dataset of molecular sequences of three gene (DNA) fragments conducted across the superfamily Conoidea. Tucker and Tenorio’s proposed classification system for the cone shells and their allies (and the other clades of Conoidean gastropods ) is shown in Tucker & Tenorio cone snail taxonomy 2009.
