The Tellin-like Sanguin Shell – Sanguinolaria tellinoides is a species of saltwater clam in the family Psammobiidae. It is a common and widespread bivalve found in intertidal and shallow subtidal zones.

Description & Characteristics

The Sanguinolaria tellinoides has an elongated, oval shell with a smooth, glossy surface. The shell is typically white or cream-colored, sometimes with a faint pinkish tinge. It can reach a maximum size of about 50 millimeters in length. The shell is characterized by its thin, fragile nature and the presence of fine, concentric growth lines. The Sanguinolaria tellinoides possesses a pointed anterior end and a more rounded posterior end. This bivalve exhibits a slightly curved dorsal margin and a rounded ventral margin. The hinge line of the shell is straight and bears a series of small teeth, which are used for locking the two valves together.

Habitat and Occurrence

The Sanguinolaria tellinoides is typically found in intertidal (Eulittoral) habitats, specifically the intertidal zone between the high and low tide lines characterized by the alternation of low and high tides. This species prefers sandy or muddy substrates and is often found buried within the sediment. The Sanguinolaria tellinoides can also be found in shallow subtidal zones, up to depths of 10 meters. Its presence in these marine zones reflects its adaptability to environments with varying levels of exposure to air and water.

Taxonomy

The species Sanguinolaria tellinoides belongs to the Class: Bivalvia, Order: Cardiida, and Family: Psammobiidae. This classification places the Sanguinolaria tellinoides within a group of marine bivalves known for their diverse adaptations and ecological roles within their respective environments.

Feeding

The Sanguinolaria tellinoides is a deposit feeder and filter feeder, meaning it obtains its food from the surrounding environment. It feeds on a variety of organic matter, including plankton, algae, and sediment. The Sanguinolaria tellinoides utilizes its gills to filter out food particles from the water column. The bivalve also extends its siphon into the sediment to obtain food particles. This feeding strategy contributes to the overall nutrient cycle and ecosystem dynamics within its habitat.
