Infundibulops erythraeus, common name : the Red Sea top shell, is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[2]
Infundibulops erithreus is a spelling variation.
Description
The shell size varies between 20 mm and 50 mm It feeds on algae and is often seen by divers.[3] The conical shell has a false-umbilicate shape. It is rather thin and inflated. The apex is acute. The shell has about seven somewhat concave whorls. They are generally traversed by several conspicuously granose lirae in the middle, a little gibbous above and below. They are obliquely undulate below the sutures, and frequently on the periphery also. The whole surface is more or less finely spirally lirate, the liras subgranulose. The base of the shell is convex, concentrically lirate with about 7 granose narrow lirae. Their interstices are generally occupied by concentric striae. The color of the shell is cinereous grayish or pinkish, striped and maculated above with reddish; unicolored pinkish or radiately marked below. The aperture is large, smooth and pearly within. The basal lip is simple. The columella is oblique and very deeply inserted. Its entire edge is nearly straight, not dentate. The umbilical tract is deep, narrow, pearly. and bears a single strong spiral white rib near its base, which does not attain the edge of the columella. [4]
Distribution
This species is distributed in the Red Sea, in the Indian Ocean (along the Aldabra atoll) and in the Mediterranean Sea (along Greece)
