Habitat: it lives associated with Anemonia sulcata, Cladocora coespitosa, Balanophyllia europaea. Distribution: common enough in the infralittoral zone all over the Mediterranean.
Imaged shells: it was found associated with Anemonia sulcata in a few metres depth at Antignano, to the South of Leghorn (Tuscany - Italy). Notes: shell solid, globose, more or less turrite, axial ribs solid, oblique, crossed by little cords running, squamous. Siphonal canal almost straight. Internal lip finelly denticulated. Dirty white in colour pattern, sometimes inside of mouth rosy in colour. Operculum dark red. Protoconch made by about four whorls, the first of which (protoconch I) is smooth and the other ones (protoconch II) have two spiral carinas crossed by several little axial ribs oblique. Radula missing. The animal is snow-white in colour. As far as this species is concerned two different forms are known which are recognizable due to their sizes, to ecology and to reproduction biology. The form bigger in sizes can be found associated with sea anemones on which it feeds piercing the walls of the base. The form smaller in sizes lives on Scleractinia on which it feeds inserting its proboscis inside, sucking the predigested contents. Nevertheless DNA analyses proved the conspecificity of the two forms.
The only Mediterranean species alike is C. panormitana mainly recognizable since it is smaller in sizes, it is less turrite, usually it is yellow rosy in colour pattern as per the operculum and it lives in deeper waters.
The adult specimens measures reach 40 mm as far as the forms bigger in sizes are concerned, and 9-10 mm as far as the forms smaller in sizes are concerned.
