Sirenilidae

Sirenilidae is a family of marine bivalve mollusks, commonly known as shipworms. These organisms are notable for their ability to bore into and degrade wooden structures, making them significant in the fields of marine biology, ecology, and conservation. The family includes several genera, with the most well-known being Sirex, which contains species like Sirex noctilio, the European shipworm. These shipworms are ectoparasites, attaching themselves to wooden structures and using their radula to bore tunnels, which they then inhabit. The family is characterized by their elongated, cylindrical shells, which are often found in clusters on the wooden substrate. Sirenilidae are found in both freshwater and marine environments, with a global distribution. Their impact on wooden structures, including historic ships and marine infrastructure, has led to significant research into their biology, ecology, and control methods. The family's unique life cycle, which includes a free-swimming larval stage, and their ability to adapt to various environments, make them a subject of interest in marine biology and conservation efforts.
