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]
