Shell with a moderately high spire and a large, slightly inflated body whorl. Spire whorls with a faint keel which disappears on the body whorl of the adults; early whorls also with fine axial folds. Aperture elongated, posteriorly notched, anteriorly with a very shallow subterminal fold near the siphonal canal, and a short, widely open siphonal canal. Inside of aperture with distinct, crowded grooves on both the columellar edge and the lip.
whitish background, and brown markings organized to form irregular flames, more intense along several spiral bands.
common size :
up to 35 mm in the Indo-Pacific, the Mediterranean adult specimen 18.6 x 11.3 mm.
This species is distinguished from S. persicus by the more inflated profile of the body whorl, the shallower subterminal fold of the aperture (on adults) and the presence of grooves inside the aperture. There are several similar Indo-Pacific species, of which the taxonomy is confusing (see Abbott, 1960).
BIOLOGY / ECOLOGY
Larvae are planktotrophic, ensuring long-distance dispersal. All Strombus species are herbivorous, feeding on algae.
in the Indo-Pacific, this species lives in sheltered back-reef areas.
