Shell biconical, with a moderately high spire and a large body whorl. Spire whorls with a definite keel, which is continued on the body whorl at a short distance from the suture; early whorls also with axial folds. Aperture elongated, posteriorly notched, anteriorly with a subterminal fold near the siphonal canal, and a short, widely open siphonal canal.
whitish background, and brown markings organized to form unequal spiral bands.
common size :
35 to 45 (common), to 50 mm (max.).
Among the Mediterranean species, this species only resembles Conus, from which the shells are easily recognized by the wider aperture with an additional notch next to the canal. The Mediterranean immigrant belongs to a difficult Indo-Pacific species complex, which is discussed by Moolenbeek and Dekker, 1993. Crucitti and Rotella (1991) have studied biometrically a population from the Gulf of Iksenderun, and questioned the need for separating the Mediterranean population at the subspecific level.
BIOLOGY / ECOLOGY
Larvae are planktotrophic, ensuring long-distance dispersal. All Strombus species are herbivorous, feeding on algae. Studies on the biology of the species along the Syrian coasts showed that it produces as high as 58% of the total community respiration and 75% in total biomass (reaching up to 93%) (Kucheruk and Basin, 1999).
in the Mediterranean, low-energy environments of shallow bays, on mixed (rock/sand/mud) bottoms.
