Tubeworms (Serpulidae, Polychaete) collected from sewage outfalls, coral reefs and deep waters off the Hawaiian islands, including a new Hydroides species.
Bailey-Brock, Julie H.
Quantitative benthic samples collected near sewage outfalls off Oahu contained two species of small, fragile serpulid tubeworms previously unknown from Hawaiian waters. One is a new species of Hydroides without an opercular funnel, the other is Josephella marenzelleri, a broadly distributed but easily overlooked serpulid. Retrieval of these species is attributed to the use of a van Veen grab and elutriation and sieving to separate the polychaetes from the sediment. Another unrecorded small serpulid species, Rhodopsis pusilla, was found growing on a hard foliaceous sponge, in a cave, on a shallow reef off the Kona coast of Hawaii. Lava rocks collected with a submersible off southeast Oahu (330 m depth) have yielded another little known serpulid species, Filogranula gracilis.
