Syllids

Syllids are a family of marine bivalve mollusks belonging to the order Pteriomorphia. They are characterized by their distinctive, often elongated shells, which are typically asymmetrical and have a distinctive hinge structure. The family includes several genera, with the most well-known being Syllia, which is found in both the Atlantic and Pacific Oceans. Syllids are typically small to medium-sized, with shell lengths ranging from a few millimeters to about 5 centimeters. They are often found in shallow waters, buried in sand or mud, and are known for their ability to burrow and move through the sediment. Syllids are filter feeders, using their siphons to draw in water and filter out food particles. They play an important role in the ecosystem by recycling nutrients and contributing to the health of the sediment. Despite their ecological significance, syllids are not well-studied, and much remains unknown about their biology and behavior.
