Chestnut Turban

Turbo castanea

Chestnut Turban is a species of sea snail characterized by its solid, imperforate shell that has an ovate-conic shape. The shell can reach a maximum length of 55 mm and displays a range of colors including orange, brown, and gray, often with white or brown markings. The shell's surface is adorned with numerous spiral lirae, which may bear small spines, making it distinct from similar species. The aperture of the shell is white and subcircular, with no umbilicus present, and the columella features a heavy white callus. The operculum is castaneous with four rapidly increasing whorls, further aiding in identification.  This species is found in a variety of habitats across the Western Atlantic, including regions from North Carolina to Brazil. It thrives in shallow subtidal environments, often on sandy bottoms, coral rubble, and in seagrass beds. The typical depth range for Chestnut Turban extends from 0 to 141 meters, with most occurrences recorded shallower than 40 meters. It is commonly found in tropical waters, particularly in areas like the Caribbean Sea, Gulf of Mexico, and along the coasts of Central and South America.  Chestnut Turban feeds primarily on algae and organic matter, utilizing its grazing behavior to consume food from the substrate. The species is known to be abundant, and its reproductive strategy involves broadcasting eggs into the water, where they develop into planktonic larvae before settling down as juveniles. Divers encountering this species may observe it resting on the seafloor or grazing on algae, often in the company of other benthic organisms. The conservation status of Chestnut Turban is not evaluated.
