}}Astralium latispina is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.[1] DescriptionThe length of the shell varies between 30 mm and 75 mm. The imperforate shell has a conic shape. It is greenish, brown maculated. The seven whorls are subplanate, obliquely costulate below the sutures, then with two beaded spiral lirae. The margins of the whorls are exserted, expanded, compressed, armed with triangular spines. The body whorl is sharply carinate. The base of the shell is radiately lamellose and ornamented with three or four granose concentric costae. The umbilical area is depressed, pale greenish or yellowish. The oblique aperture is angulate. The oval operculum is on the outside white, smooth, with a single arcuate wide rib. On the inside it is flat, chestnut colored. The nucleus is submarginal.[2] DistributionThis species occurs in the Gulf of Mexico and in the Atlantic Ocean off Brazil. References1. ^Rosenberg, G. (2012). Astralium latispina (Philippi, 1844).
