Dosinia nedigna is a species of saltwater clam, a type of marine bivalve mollusk. It is a member of the family Veneridae, commonly known as the Venus clams, a diverse group of bivalves found in various marine environments worldwide.
Description & Characteristics
Dosinia nedigna exhibits a characteristic shell shape typical of its family. The shell is generally round or oval, with a smooth, slightly convex exterior surface. It is moderately thick and possesses concentric growth lines, indicating the clam’s growth stages. The coloration can vary, ranging from light beige to a pale brownish-yellow, often adorned with intricate patterns and subtle markings.
Habitat and Occurrence
Dosinia nedigna is a common inhabitant of sandy and muddy bottoms in the intertidal and shallow subtidal zones. They are typically found in depths ranging from the low tide mark to around 30 meters, inhabiting both coastal and offshore environments. The species is a prominent presence in the neritic zone, which encompasses the marine waters above the continental shelf, and can be found in various marine biogeographic regions.
Taxonomy
Dosinia nedigna is classified as follows: belonging to the Class Bivalvia, Order Venerida, and Family Veneridae. These groupings place the species within a larger framework of marine bivalve mollusks, highlighting its evolutionary relationships and shared characteristics with other members of its taxonomic family.
Feeding
Dosinia nedigna, like most bivalves, is a filter feeder. They obtain their sustenance by drawing water into their bodies through a siphon, filtering out microscopic plankton, algae, and organic matter. This process plays a vital role in the marine ecosystem, contributing to water clarity and nutrient cycling.
