Raphitomidae
Raphitomidae is a family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.
Bouchet, Kantor et al. elevated in 2011 the subfamily Raphitominae to the rank of family. This was based on a cladistic analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. The family was found to be monophyletic.
Description
The Raphitomidae is the largest, most diverse and most variable taxon in the Conoidea, with the greatest number of species and the largest ecological range and largest vertical range.The shells of species in the Raphitomidae are very variable in shape and size. Similarly, shell sculpture is extremely variable, from nearly smooth to well developed spiral and axial elements and subsutural ramps. Common morphology includes apertural armature rarely well developed, inner lip usually smooth, no operculum, radular tooth hypodermic in character with marginal teeth of variable morphology.
The muscular bulb of the venom gland is always single-layered. The close relationship of Raphitomidae with cone snails, makes them an interesting candidate for the discovery of new toxins.
Another characteristic is the multispiral protoconch, which shows spiral striae on protoconch I and diagonally cancellated sculpture on protoconch II.
Some species with a paucispiral protoconch are included in the family. This is usually based on similarities in shell morphology to
species having a "raphitomine" protoconch. This determination should also ideally be founded on other attributes, such as the type of radula or foregut anatomy or their lack of an operculum.
