Pista pacifica is a species of polychaete worm in the family Terebellidae native to the coastal regions of the northeastern Pacific Ocean, from British Columbia to Southern California.[1][2] It creates vertical tubes in intertidal mud or sand[2] that can be more than two feet deep.[3] The tubes extend above the substrate, terminating in overhangs bearing many marginal tendrils.[2] The worms themselves can grow up to 37 cm long,[2] and, like all members of the family Terebellidae, they are particle feeders that use their tentacles to forage for organic detritus around their burrows.[2] The scale worm Halosydna brevisetosa may reside commensally in their tubes.[4]
