Biology:Comitas
From HandWiki
Comitas is a genus of medium-sized sea snails, which are marine gastropod molluscs in the family Pseudomelatomidae.[1]
General characteristics
The shell is generally large, usually over 50 mm in length, with broad and long axial ribs, always extending to the periphery and sometimes to the shell base. The anal sinus is moderately deep, medium broad U-shaped, on the subsutural ramp and occupying the lower part of the subsutural ramp, not on all its width, so that the deepest point is closer to shoulder than to suture. Correspondingly the sinus line in its upper part is prosocline, but convex.
Species of Comitas have a very distinctive radula, reliably distinguishing them from all other conoideans.[2]
