Gottfried Pillai Zoology Department, Natural History Museum, Cromwell Road, London SW7 5BD, United Kingdom absTracT. In 1988 Pat Hutchings of the Australian Museum, Sydney, undertook an extensive polychaete collection trip off the Kimberley coast of Western Australia, where such a survey had not been conducted since Augener’s (1914) description of some polychaetes from the region. Serpulids were well represented in the collection, and their present study revealed the existence of two new genera, and new species belonging to the genera Protula, Vermiliopsis, Hydroides, Serpula and Spirobranchus. The synonymy of the difficult genera Spirobranchus, Pomatoceros and Pomatoleios is also dealt with. Certain difficult taxa currently referred to as “species complexes” or “species groups” are discussed. For this purpose it was considered necessary to undertake a comparison of apparently similar species, especially of Spirobranchus, from other locations in Australia and the Indo-West Pacific region. It revealed the existence of many more new species, which are also described and discussed below. Pillai, T. Gottfried, 2009.

Zoological Studies 34(2): 117-125. The distribution of Spirobranchus giganteus corniculatus (Hove), a widely distributed tube-building serpulid, on the coral reefs of southern Taiwan was studied by the transect sampling method. Two reef sites in Nanwan Bay, one with a high degree of physical disturbance and the other with a lower degree of disturbance, were surveyed. The spatial distri bution of S. giganteus corniculatus on coral colonies was also analyzed using distance to nearest neighbor. The results show that S. giganteus corniculatus is distributed nonrandomly among coral species. Four species, Porites tutee, P. lobete, P. lichen, Montipora informis, are frequently colonized by the worm. About 30 species are occasionally colonized and many coral species are not colonized. Coral species which are frequently colonized by the worm are competitively subordinate. The spatial distribution of S. giganteus corniculatus on a coral colony is related to the number of worms with a tendency toward clustering with in creasing number of worms per colony. In addition, most worms were found at intermediate depths (6-17 rn) where the reef surface was flat and there were more colonizable scleractinians. The distribution and abun dance of S. -

Northwestern Hawaiian Islands/Kure Atoll Assessment and Monitoring Program
Northwestern Hawaiian Islands/Kure Atoll Assessment and Monitoring Program Final Report March 2002 Grant Number NA070A0457 William j. Walsh1, Ryan Okano2, Robert Nishimoto1, Brent Carman1. 1 Division of Aquatic Resources 1151 Punchbowl Street Rm. 330 Honolulu, HI 96813 2 Botany Department University of Hawai`i Mānoa Honolulu, HI 96822 2 INTRODUCTION The Northwest Hawaiian Islands (NWHI) consist of 9,124 km2 of land and approximately 13,000 km2 of coral reef habitat. They comprise 70% of all coral reef areas under U.S. jurisdiction. This isolated archipelago of small islands, atolls, reefs and banks represent a unique and largely pristine coral reef ecosystem. The islands support millions of nesting seabirds and are breeding grounds for the critically endangered Hawaiian monk seal and threatened green sea turtle. The reefs include a wide range of habitats and support a diverse assemblage of indigenous and endemic reef species, many of which have yet to be described. Kure Atoll, located at the northwestern end of the NWHI chain (approximately 28º 25’ N latitude and 178º 20’ W longitude) is the northernmost atoll in the world. The atoll is located 91 km northwest of Midway Islands and nearly 1,958 km northwest of Honolulu. It is a nearly circular atoll with a diameter of 10 km (6mi). The outer reef is continuous Figure 1. IKONOS satellite image of Kure Atoll 3 and almost encircles the atoll’s lagoon except for passages to the southwest (Fig. 1). An emergent rock ledge consisting primarily of coralline algae and algally bound and encrusted coral is present along some sections of the reef crest. -

The organisms include a calcareous-tube polychaete Spirobranchus corniculatus (Grube), a sand-tube sabellariid polychaete, Idanthyrsus sp., a vermetid gastropod Dendropoma maxima Sowerby, a pecten bivalve Pedum spon- dyloideum Gmelin, and a coral barnacle Cantellius sp. The three tubicolous former species showed growth in various directions, and 15 to 20 years (S. corniculatus), 8 years (Idanthyrsus sp.), and 15 years (D. maxima) longevity were reliable estimates in this study. In contrast, the pecten bivalve and the coral barnacle showed lesser longevities, usually less than 7 years, and they grew vertically in almost the same direction as the host coral; thus, their growth rates can be estimated roughly by shell or slit-like hole length in relation to average host coral growth. We present here a new and practical method to esti mate age and longevity of non-boring coral infauna, and we discuss marine organism growth and lon gevity with emphasis on polychaetes.

Many people generally assume that a worm is always ugly. Nonetheless, particular species of polychaete marine worms (Annelida) belonging to the family Serpulidae and Sabel/idae reveal something different. They are showy, beautiful and attractive. Moreover, they are unlike a worm. For many years, these species of seaworms have been fascinating many divers. For their unique shape, these animals are well known as jan worm't'peacock worm'Z'feather-duster worm' (Sabella pavonina Savigny, 1822) and 'christmas-tree worm' iSpirobranchus giganteus Pallas, 1766).
