gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda ().
This class comprises snails and slugs from saltwater, from freshwater, and from land. T ...
mollusk in the

Description
The size of the shell varies between 6 mm and 10 mm. The umbilicate shell has a globose-conic shape. It is coral-red or brown, marked beneath the
sutures with narrow flames of white and maculations of brown, and on the base dotted with white. But the species exhibits a considerable variation in color. The conic
spire is acute. The sutures are subcanaliculate. The five to six
whorl
A whorl ( or ) is an individual circle, oval, volution or equivalent in a whorled pattern, which consists of a spiral or multiple concentric objects (including circles, ovals and arcs).

body whorl
The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk.

is rounded, encircled by 14 or 15 conspicuously granose equal ridges, the interstices finely obliquely striate, and with more or less obvious spiral striae. The oblique
aperture is subtetragonal. The outer
lip is plicate within, dentate above, the tooth usually bifid. The basal margin is curved and crenulate within. The
columella is inserted deep in the rather narrow
umbilicus, bearing a strong dentiform fold above and a large quadrangular biplicate tooth at the base. The parietal wall is wrinkled. The white umbilicus is smooth within and has a crenulate margin.
