Featherdusters, scientifically known as Bispira viola, are marine worms belonging to the family Sabellidae. These fascinating creatures are characterized by their distinctive feather-like tentacles, which they use to filter food from the water. They are a common sight in many marine environments, playing a vital role in the delicate balance of these ecosystems.
Description & Characteristics
Bispira viola, also known as Featherdusters, are tube-dwelling polychaetes. They can grow to a maximum size of around 5 cm in length, with their bodies enclosed in a tube they build themselves from sand and mucus. The most striking feature of Bispira viola is their crown of feather-like tentacles, called radioles, which they extend out of their tubes to filter food from the water. These radioles are covered in tiny cilia, which create a current that draws food particles towards the worm’s mouth. When disturbed, the worm quickly retracts its radioles into its tube, providing a protective mechanism.
Habitat and Occurrence
Bispira viola typically inhabits the subtidal, sublittoral, infralittoral, and deep zones of the oceans, extending from the lower limit of the intertidal zone to the shelf edge at about 200 m water depth. This extensive range places Bispira viola in the neritic zone, where it thrives in a variety of marine environments. Their presence in these zones highlights their adaptability and their crucial role in maintaining the delicate balance of these ecosystems.
Taxonomy
Bispira viola belongs to the Class: Polychaeta, Order: Sabellida, and Family: Sabellidae. Polychaetes are a diverse group of segmented worms, commonly known as bristle worms. The Sabellida order encompasses tube-dwelling polychaetes with feather-like tentacles, while the Sabellidae family further classifies those that possess radioles with a distinct feather-like appearance.
Feeding
Bispira viola are filter feeders, using their radioles to trap food particles from the water column. Their diet consists primarily of detritus, phytoplankton, plankton, and zooplankton. The tiny cilia on their radioles create a current that directs these food particles toward their mouths. Their feeding habits play a crucial role in marine ecosystems, helping to cycle nutrients and maintain the balance of the food web.
