Nephtyids [Nephtyidae]

Description

Nephtyidae, also known as sand worms or clam worms, are a family of polychaete worms known for their ability to burrow rapidly into the sand or mud. They have muscular, elongated bodies and are characterized by their strong jaws and the presence of paired, paddle-like parapodia that aid in burrowing and swimming. These worms are predators or scavengers, feeding on a variety of small invertebrates.
