The relationship was found in five localities across a total of 22 sites where O. annulata was collected. The polynoids collected were similar to the Western Atlantic scale-worm Malmgreniella variegata, which was previously recorded as commensal of O. annulata on the Pacific side of Panama, although they differ in colour pattern and the presence of notochaetae with a unidentate tip. The prevalence of infestation was 5% and the intensity was 1.20. Experimental observations suggest that the behaviour of the scale-worm on O. annulata could be affected by light conditions, and that the commensal had a preference for its host over other ophiuroid species. More studies should be carried out to determine the taxonomic status of M. cf. variegata in the Eastern Pacific and to further elucidate the commensal-host relationship between this scale-worm and O. annulata.
