Giant feather-duster worm (Pseudobranchiomma longa)

Details of the spiral whorls of feeding appendages of the tube worm. Old Woman’s River, Eastern Cape (2021) – iNaturalist

Head crowned with two magnificent spiral whorls of feeding appendages. Commonly purple, white or orange. The absence of tiny external flaps (or stylodes) from the branches of the crown helps distinguish this species. Body encased in a parchment-like mucous tube (which typifies the family Sabellidae).

About 120 mm long.

Solitary, living in shady rock-crevices. Uses its fan to catch and sort food particles, eating only the smallest and most nutritious.
