About Tritia neritea (Linnaeus, 1758)
The shell of Tritia neritea ranges in length from 5 mm to 25 mm. It is hemispherical, smooth, and depressed in shape, convex on the upper surface and flattened on the underside. Its blunt spire is made of four indistinct, entirely smooth whorls. The ovate aperture is reddish, rather small, and obliquely notched at the edge. The outer lip is smooth with a slight defined margin. The columella curves inward near its middle, and is covered with a wide, reddish, nearly circular callus that extends onto the body of the body whorl. Shell color is slightly variable, but individuals are typically yellowish or reddish white, marked with brown lines and two descending, either interrupted or articulated bands: one band encircles the suture, and the other borders only the shell's outer circumference. The epidermis is thick and brown. This species is found in the Mediterranean Sea and the Black Sea.
