Bassina
Bassina is a genus of marine bivalve molluscs belonging to the family Veneridae, commonly known as clams. These species are found in intertidal and shallow subtidal environments along the coasts of Australia, New Zealand, and South Africa. Bassina species are typically small to medium-sized clams with a distinctive, often triangular, shell shape. They play an important role in marine ecosystems as filter feeders, contributing to water clarity and nutrient cycling.
Characteristics
Bassina clams exhibit several distinct characteristics that distinguish them from other venerid species. They typically have a smooth or lightly sculptured shell surface, often with a prominent umbo (the highest point of the shell). The shell can range in color from white to brown or gray, with varying patterns of lines or markings. The hinge of the shell contains teeth that are characteristic of the genus, providing structural support and aiding in shell closure.
Environments
Bassina clams inhabit a variety of environments, including:
- Intertidal zones, where they are exposed to air and water fluctuations
- Shallow subtidal areas, where they are submerged most of the time
- Sandy or muddy bottoms, where they burrow into the sediment
- Seagrass meadows, where they find food and shelter
Common Names
While Bassina is the scientific genus name, these clams are commonly referred to by various names depending on the species and location, including:
- Bassina (general name)
- Cockle
- Pipi (in Australia)
