About Turbo petholatus Linnaeus, 1758
Turbo petholatus Linnaeus, 1758 has shells that measure between 30 mm and 100 mm in length. The imperforate shell is solid, polished, and shining. Its base color is rich brown, with varied ornamentation of dark bands interrupted by white blotches and narrow stripes. The five whorls are flattened below the suture, and are sometimes carinated above. The aperture makes up approximately half the total length of the shell; it is circular and pearly on the inside. The peristome and columella are tinted greenish-yellow. The shell pattern of this species is very similar to that of Turbo moolenbeeki, especially in the brown form of Turbo petholatus. The operculum is circular, with four whorls and a nucleus located one-third of the way across the operculum's face. The outer surface of the operculum is convex and shining, bright green at the center, with brown margins on one side and white margins on the other, and it is slightly granulose around the edges. This species is distributed in the Red Sea, the Indian Ocean off the coasts of Madagascar, Mozambique, Chagos, and Mauritius, the West Pacific, and along the Australian coast from Western Australia to southern Queensland.
