Sabellaria
Sabellaria is a genus of marine polychaete worms belonging to the family Sabellariidae. These worms are known for their ability to build extensive, complex reefs from sand grains and other marine debris, creating habitats for numerous other species.
Common Names
Common names for Sabellaria species include:
- Sand tube worms
- Tube worms
- Sandcastle worms
Characteristics
Sabellaria worms possess several distinctive features:
- Tube-dwelling: They construct sturdy, cemented tubes from sand grains, shell fragments, and other marine debris. These tubes provide protection and stability for the worms.
- Colonial lifestyle: Sabellaria species often form dense colonies, with numerous individuals living together in close proximity, contributing to the formation of reefs.
- Filter feeders: They use their fan-like tentacles to filter food particles from the surrounding water.
- Bioturbation: Through their tube construction and feeding activities, Sabellaria worms significantly influence sediment dynamics and bioturbation in marine environments.
Environments
Sabellaria species are found in a variety of marine environments, including:
- Intertidal zones: Sabellaria reefs are commonly observed along the shores of rocky coasts and estuaries.
- Subtidal zones: They can also be found in shallow subtidal areas, extending to depths of several meters.
- Temperate and tropical regions: Sabellaria species have a worldwide distribution, occurring in both temperate and tropical regions.
