Abstract: The holotype of Lysiosquilla crassispinosa Fukuda, 1909, which is currently assigned to the genus Bathysquilla Manning, 1963, was discovered in the collection of the University Museum, University of Tokyo. The discovery of the specimen invalidates the selection of the neotype of B. crassispinosa. Several other stomatopod specimens cited in Fukuda'papers and now located in the University Museum, University of Tokyo, are re-identified. Gonodactylus childi Manning, 1971 is reported for the first time from Japanese waters.

Abstract: Effective transplantation techniques are a key step in developing in situ manipulative studies. Gorgonian octocorals have biological and morphological features suitable for such studies. Therefore, three methods were employed for the transplantation of the gorgonian octocoral Melithaea flabellifera. Method 1 was for the reattachment of a gorgonian to its original stem. Methods 2 and 3 were for the transplantation to hard substrata such as natural rock walls(Method 2)and concrete artificial reefs(Method 3). These meth ods remarkably shortened the time needed for the underwater manipulative work.Throughout the study period, the persistence rates of the transplanted gorgonians were high except for the period when typhoons impacted when also natural dislodgements increased. Growth rates during the eight-week study period were small, but positive. These results showed the validity of the transplantation methods. The methods may also be applicable to other erect-form sessile organisms on hard substrata such as other gorgonians, hydroids, bryozoans and algae.

Abstract: Gwangyang Bay is one of the most quickly developing coastal areas in Korea. In the 1970s, a mainly estuarine delta and tidal flats along the bay were reclaimed to develop a huge industrial complex. Therefore, the various habitats around Seomjin river estuary and the shallow water embayment in Gwangyang Bay have been seriously impacted during the last three decades by industrial pollutants and increased freshwater discharges. This study focused on the spatial variability of macrofaunal assemblages. Samples were collected along a 3km transect extending from the intertidal to subtidal zones, including an eelgrass bed.Different assemblages were identified by multi-dimensional scaling(MDS)ordination andcluster analysis. Five different communities were identified in three major habitats. The eelgrass bed and subtidal shallow water embayment contained discrete communities. The unvegetated tidal flat was subdivided into three different communities according to tidal elevation. A total of 254 species of benthic macrofaunal invertebrates was recorded in this survey. Polychaetes dominated species richness, but molluscs dominated abundance and biomass. Macrobenthic biodiversity was highest in the eelgrass bed(48.3 species/0.1m²), followed by the subtidal zone(45.4 species/0.1m²)and unvegetated tidal flat(24.6 species/0.1m²). Each community can be identified by a few characteristic species.

Abstract: Growth mode, foraging activities and reproductive characteristics of Cronia margariticola(Gastropoda:Muricidae)were investigated in the rocky intertidal seashore of Shirahama, Wakayama, Japan. C. margariticola, which reached sexual maturity at about 16mm in shell height, was found to have a distinct annual reproductive cycle. Mounting was frequent in May and June, and oviposition, primarily into beds of the mussel Hormomya mutabilis, took place during June and July. Feeding was observed from April through October, but was restrained during the peak reproductive season. Monthly size distribution showed that the growth rate was decelerated after achieving sexual maturity size. Growth measurement of tagged animals revealed that juveniles continued growing from March through January, taking 2 to 3 years to reach adult size after hatching. In contrast, adults grew from July through January and reached the peak in August and September, allocating energy obtained by feeding for reproduction in the spring and for growth in the fall. This energy allocation strategy was discussed with relation to the seasonal fluctuation of the availability of food resource for C. margariticola, which usually employs a parasitic foraging strategy.
