In members of this genus thoracic and abdominal interramal eye spots present while radiolar eyes are absent. Abdominal neurochaetae are arranged in a C-shape. In living specimens, identification is easy since the radiolar crown when expanded underwater appears as a tuft, not obviously helical (whereas in the introduced species Sabella spallanzanii it is a very obvious helix). Preserved specimens are more difficult to distinguish and require careful observation of chaetal arrangement. Body up to about 1 cm long.
Several different colour forms of this common, large, fan worm occur around south-eastern Australia. In eastern Victoria, specimens have a pale to white fan, while further west and in Port Phillip Bay specimens are brown-orange. Preliminary DNA studies indicate that several new species might one day be described.
Port Phillip Bay and other similar coastal habitat, inshore and continental shelf.
