Calliotropis granolirata explained
Calliotropis granolirata, common name the Cape cog shell, is a species of sea snail, a marine gastropod mollusk in the family Calliotropidae.
Description
The length of the shell reaches 25 mm.
The shell is small, featuring a conical spire and a rounded base. It is sculpted with prominent spiral cords that bear well-developed granules. The spire whorls have three cords, including one at the periphery, while the base is adorned with four cords. The umbilicus is closed, and the aperture displays a nacreous (mother-of-pearl) sheen when the shell is fresh.
Coloration is uniformly milky-white to pale buff, with a matte, non-lustrous finish. [1]
Distribution
A marine species endemic to South Africa, it has been reliably recorded only from deep waters off the Cape Agulhas–Cape Point region, at depths reaching up to 2,750 meters.
