The Polished Green-Ridged Turban Shell belongs to the Gastropod family.
These species have a flat shell and pearlised mouth which has been polished to give a stunning effect.
A lovely addition to your own collection or would make a lovely gift.
Due to the large amount of individual variations among these species some collectors like to see how many of the different types they can collect.
Due to their size and shape these shells are also perfect for Hermit Crabs.
Popular amongst children and teachers as classroom art projects.
Would also look pretty in a bowl full of shells on a shelf or on your coffee table.
The shells of species in this genus are more or less highly conspiral, thick, about 20–200 mm, first whorls bicarinate, last whorl large often with strong spiral sculpture, knobs or spines, base convex, with or without umbilicus. Species in this genus have a round aperture and a solid, dome-shaped calcareous operculum. This circular operculum commences as a multispiral disc, like that of a Trochus, upon the outer side of which is deposited a thin calcareous layer by a lobe of the foot which projects partly over it. This arrangement produces an operculum which exhibits all the whorls beneath, but which is only feebly, or not obviously spiral above, from the more or less general distribution of the calcareous matter.
The radula is broad and generally rather short. The median, lateral and marginal teeth are always present. The central teeth contain no cusps. The median tooth consists of a narrow oblong quadrate basal plate, frequently with accessory plates of various forms, to the lower end of which is attached the oval body of the tooth,—a simple plate without cusp, bearing supporting wings at the sides. Frequently the central teeth are asymmetrical in this group. The laterals bear supporting wings at their outer angles, and are various in form, with or without cusps. The inner marginals are very large, with large cusps.
The first Turbo species were found in the Upper Cretaceous, approximately 100 million years ago.
