The gentile unfurling of a feather duster worm. Any stimulus, wether it be a passing shadow or a perceived predator, or a pressure wave from anything moving nearby, will rapidly send the feather duster worm retracting back into its tube in the blink of an eye. Waiting for them to emerge and unfurl their delicate plume can seriously test your patience - sometime one minute, other times ten. But it’s a brief moment of beauty if you’re there to witness it! #featherdusterworm #coralreef #scubadiving

Sabellidae (feather duster worms) are a family of sedentary marine polychaete tube worms in which the head is mostly concealed by feathery branchiae. Sabellids build tubes out of a tough, parchment-like exudate, strengthened with sand and bits of shell. Sabellidae tend to be common in the intertidal zones around the world. Their oldest fossils are known from the Early Jurassic. | Indus Scuba
