Feather Duster Worm
Sabellidae · also called fan worm
Extending a brightly coloured, feathery crown from a soft tube of its own making, a feather duster worm filters food and breathes at the same time, vanishing instantly back inside at the faintest hint of a passing shadow.
Overview
The feather duster worm, family Sabellidae, is a tube-dwelling filter feeder native to ocean habitat recorded across tropical and temperate waters worldwide. Its striking feathery feeding crown, lightning-fast retreat response, and ability to regenerate a lost crown make it one of the more visually distinctive and resilient tube-dwelling invertebrates found anywhere in the ocean.
A crown that does double duty
The feather duster worm’s colourful crown is not simply decorative, serving as both a feeding net for capturing drifting plankton and a gill for breathing, all while remaining ready to vanish into its tube the instant a shadow signals possible danger.
Status
Least Concern, remaining widespread across suitable ocean habitat worldwide.
Feather Duster Worm: common questions
Why is it called the feather duster worm?
This family extends a brightly coloured, feathery crown of tentacles from its tube to filter feed, a striking display resembling a feather duster that gave the group its common name.
How fast can a feather duster worm hide?
This family can retract its feathery crown back into its protective tube almost instantly at the first hint of a passing shadow or disturbance, reappearing only once it senses the danger has passed.
Does the feather duster worm's crown do more than just catch food?
Yes, this family uses its feathery crown not only for feeding but also for respiration, exchanging gases with the surrounding water at the same time it filters out food particles.
Can a feather duster worm survive losing its crown?
Yes, this family is capable of regenerating its feathery crown if it is damaged or lost, allowing the worm to recover after an attack that removes this exposed and vulnerable feeding structure.
