Turbo marmoratus Linnaeus, 1758

Turbo marmoratus is a large marine snail. It has a thick, heavy shell, dextrally coiled and roughly turban-shaped. The body whorl is large, with a small, pointed spire. The length of the shell is roughly equal to the width. The spire whorls are rounded, but the body whorl has an angular shoulder. The shell is marked with fine axial growth lines and three large spiral ribs, bearing blunt tubercles. The aperture is very large, forming two-third of the length of the shell, and is nearly circular, surrounded by a thick pearly lip
