Naria marginalis is a species of sea snail, a marine gastropod mollusk in the family Cypraeidae, the cowries. Naria marginalis is a common species found in many locations throughout the Indo-Pacific region.
Description & Characteristics
Naria marginalis is a medium-sized cowrie, typically reaching a maximum size of about 45 millimeters in length. The shell is ovate in shape and has a smooth, glossy surface. The dorsal surface of the shell is usually a pale brown or cream color, with a series of dark brown spots and blotches. The ventral surface of the shell is white and has a distinctive, raised margin that gives the species its name. The aperture of the shell is long and narrow, and the teeth on the inner lip are small and numerous.
Habitat and Occurrence
Naria marginalis is found in the intertidal zone and shallow subtidal waters of the Indo-Pacific region. It is a common species in many tropical and subtropical areas, including the Red Sea, the Indian Ocean, the Pacific Ocean, and the Caribbean Sea. The species typically inhabits coral reefs, rocky shores, and seagrass beds, making it a prevalent presence in these aquatic ecosystems. Naria marginalis is commonly found in the neritic zone, the area of the ocean that extends from the shoreline to the edge of the continental shelf.
Taxonomy
The species Naria marginalis belongs to the Class: Gastropoda, Order: Littorinimorpha, and Family: Cypraeidae. The family Cypraeidae is a diverse group of marine snails that are characterized by their smooth, glossy shells. Cowries are found in a wide range of habitats around the world, and they are known for their beautiful and varied colors and patterns.
Feeding
Naria marginalis is a herbivorous species that feeds primarily on algae. The snail uses its radula, a ribbon-like structure in its mouth, to scrape algae off of rocks and other surfaces. Naria marginalis also feeds on detritus, which is decaying organic matter. The species plays an important role in the ecosystem by helping to control the growth of algae.
