See text Conoidea is a superfamily of predatory sea snails, marine gastropod mollusks within the suborder Hypsogastropoda.

This superfamily is a very large group of marine mollusks, estimated at 340 recent valid genera and subgenera, and considered by one authority to contain 4,000 named living species.

[6] The radula types[7] are as follows: In 2009, a proposed new classification of this superfamily was published by John K. Tucker and Manuel J. Tenorio.

Both classifications were based upon cladistical analyses and included modern taxonomic molecular phylogeny studies.

[9] In 2009 John K. Tucker and Manuel J. Tenorio proposed a classification system for the cone shells and their allies (which resorb their inner walls during growth) based upon a cladistical 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.

[11][12][13][14][15][16][17] This 2009 proposed classification system also outlined the taxonomy for the other clades of Conoidean gastropods (that do not resorb their inner walls), also based upon morphological, anatomical, and molecular studies, and removes the turrid snails (which are a distinct large and diverse group) from the cone snails and creates a number of new families.
