Thracia pubescens is a species of marine bivalve mollusc belonging to the family Thraciidae. This species is known for its distinctive characteristics and its relatively widespread distribution in certain marine environments.
Description & Characteristics
Thracia pubescens exhibits a characteristic oval-shaped shell with a smooth, slightly inflated exterior. The shell’s color can range from white to pale yellowish-brown, and its surface may bear subtle growth lines. The maximum size of Thracia pubescens is typically around 40 mm in length.
Habitat and Occurrence
Thracia pubescens is a common inhabitant of sandy and muddy bottoms in intertidal and subtidal zones. It is often found buried in the sediment, with only its siphon extending above the surface. This species is particularly prevalent in the infralittoral zone, which is the marine environment extending from the low tide mark to the depth where the seafloor is consistently covered by water. This zone is characterized by a rich diversity of marine life, and Thracia pubescens plays a role in this ecosystem by contributing to sediment turnover and nutrient cycling.
Taxonomy
Thracia pubescens is a member of the Class Bivalvia, which encompasses a vast array of marine mollusks known for their two-part shells. While not assigned to a specific Order, it belongs to the family Thraciidae, a group of bivalves characterized by their relatively thin and often fragile shells.
Feeding
Like most bivalves, Thracia pubescens is a filter feeder. It draws in water through its siphon, trapping microscopic food particles such as algae and plankton. This feeding strategy plays a vital role in maintaining water quality and the health of the marine environment.
