Septa closeli is a species of sea snail, a marine gastropod mollusk in the family Cymatiidae. It is a relatively large and distinctive species, easily recognized by its unique shell morphology and coloration.
Description and Characteristics
Septa closeli possesses a large, heavy, and robust shell that can reach a maximum size of around 100 millimeters. The shell is typically a cream-colored to yellowish-brown, often with a mottled or speckled appearance. It exhibits a characteristically wide, flaring aperture, and its outer lip is usually thickened and toothed. The shell surface is often covered in fine, spiral ridges, giving it a somewhat rough texture.
Habitat and Occurrence
Septa closeli is a marine species that inhabits the intertidal zone and shallow subtidal waters. It is commonly found on rocky shores, reefs, and seagrass beds. It is typically associated with areas with strong currents and wave action. Septa closeli has a wide geographical distribution and is found in various marine zones, including the neritic zone and the epipelagic zone.
Taxonomy
Septa closeli belongs to the Class Gastropoda, Order Littorinimorpha, and Family Cymatiidae. This family comprises a diverse group of sea snails, commonly known as tritons or tun shells. The family Cymatiidae is characterized by their large, heavy shells, often with a distinctive flaring aperture and toothed outer lip.
Feeding
Septa closeli is a carnivorous species that feeds primarily on other mollusks, particularly bivalves. It uses its strong, radula, a ribbon-like structure with rows of teeth, to bore into the shells of its prey and extract the soft tissues within. The species plays an important role in the marine ecosystem by controlling populations of other mollusks.
