Turritella sanguinea explained

Turritella sanguinea is a species of sea snail, a marine gastropod mollusk in the family Turritellidae.

Description

The length of the shell varies between 30 mm and 45 mm.

The shell is relatively large, many-whorled, and long and slender, tapering gradually toward the apex. The whorls are convex, rounded outward, and are sculpted with relatively uniform, rounded or flat-topped spiral cords. The surface is dull, and the basal angle is not marked by a stronger spiral cord. The aperture is rounded, and the outer lip is shallowly concave.

The color ranges from cream to buff, with reddish-brown dashes along the spiral cords, occasionally forming axial flame-like patterns or bands. ^[1]

Distribution

This marine species is endemic to South Africa and occurs off Port Alfred to Southern KwaZulu-Natal, South Africa at depths between 30 m and 120 m.
