About Astralium latispina (R.A.Philippi, 1844)
The shell of Astralium latispina ranges in length from 30 mm to 75 mm. It is an imperforate shell with a conical shape, and is greenish with brown patches or spots. The shell has seven whorls that are nearly flattened, and are obliquely ribbed just below the sutures, followed by two beaded spiral ridges. The margins of the whorls project outward, are expanded and compressed, and are covered with triangular spines. The body whorl has a sharp keel. The base of the shell has radially arranged ridges, and is ornamented with three or four granular concentric ribs. The umbilical area is depressed, and is pale greenish or yellowish. The oblique aperture is angular. The oval operculum is white and smooth on its outer surface, with a single wide curved rib. On its inner surface, the operculum is flat and chestnut-colored, and its nucleus is positioned near the margin. This species is found in the Gulf of Mexico and in the Atlantic Ocean off the coast of Brazil.
