Pharaonella sieboldii is a species of saltwater clam, a type of bivalve mollusk. It is a relatively small clam, reaching a maximum size of around 25 millimeters. This species is commonly found in various marine environments, playing a role in the delicate balance of these ecosystems.
Description & Characteristics
Pharaonella sieboldii possesses a characteristic shell shape, often described as oval or elongated, with a smooth, glossy surface. Its color can vary, ranging from white to pale yellow, sometimes with a hint of brown. The shell is typically thin and fragile, reflecting its adaptation to specific environmental conditions.
Habitat and Occurrence
Pharaonella sieboldii is a marine organism, inhabiting a variety of environments within the ocean. This clam is typically found in sandy bottoms, often in coastal areas. Its presence is commonly noted in the intertidal zone, the area between high and low tide marks, suggesting its adaptation to fluctuating water levels. This species is also found in shallow subtidal areas, extending its reach to depths of up to 10 meters. This distribution, encompassing both intertidal and shallow subtidal zones, highlights the adaptability of Pharaonella sieboldii to different environments within the marine ecosystem.
Taxonomy
Pharaonella sieboldii is classified within the phylum Mollusca, specifically belonging to the Class Bivalvia, Order Cardiida, and Family Tellinidae. This classification reflects its close relationship with other bivalve species, characterized by their two-part hinged shells.
Feeding
Pharaonella sieboldii is a filter feeder, extracting nutrients from the surrounding water. It utilizes its gills to collect microscopic organisms, such as algae and plankton, which constitute its primary food source. This feeding strategy plays a significant role in maintaining the balance of the marine ecosystem by regulating the population of these microscopic organisms.
