Feather duster worms build tubes out of a secreted tough fluid strengthened by sand and bits of shell. ⁣

The feather duster refers to the multicoloured crown of finely divided tentacles which are extended for feeding and breathing but are quickly retracted in the first sign of danger. ⁣

Their life cycle includes a free living microscopic larval stage that disperses from the parental site and metamorphoses into adult form. ⁣
