(of a marine worm) living in a tube.
- ‘In filter-feeding tubicolous polychaetes the buccal cavity is not eversible and there is no proboscis.’
- ‘Thus some shallow water marine annelid worms contain considerable quantities of porphyrins in their tissues, but are tubicolous or burrowing in habit.’
- ‘Spirorbis borealis, another benthic, tubicolous polychaete, releases its larvae at the first and third quarters of the moon.’
- ‘In this regard their mode of life may have been quite similar to fossil and recent species of tubicolous polychaete worms, such as serpulids.’
