The brachyuran crab Bythograeidae Williams, 1980 is common in hydrothermal vent fields worldwide and has recorded to sixteen species of six genera. In this study, we firstly determined the cytochrome c oxidase subunit 1 (CO1) DNA barcodes for the fifth species of Austinograea, A. hourdezi, from hydrothermal vent regions of the North Fiji Basin in southwestern Pacific Ocean. All CO1 DNA barcodes of A. hourdezi were identical. The interspecies variations of three bythograeid genera were 10.9-13.3% for Austinograea, 6.6-15.7% for Bythograea, and 9.7% for Gandalfus. These results would be helpful to understand taxonomy of brachyuran crabs living in hydrothermal vent fields using CO1 DNA barcodes.

Two species of crabs, Homola orientalis Henderson, 1888 and Pseudomicippe nipponica (Sakai, 1938), are described and illustrated for the first time in Korea. Homola orientalis was collected at 30 m depth by trap from Busan, and P. nipponica was collected on the intertidal region in Seongsanpo, Jejudo Island. Homola orientalis is the first species of its family in the region. The family Homoldae is characterized by a linea homolica on the carapace and they carry camouflage in the form of sponges or cnidarians with subchelate of the fourth ambulatory legs. The Korean brachyuran fauna now comprises 223 species including the new records from this study.

Three crab species, Macromedaeus orientalis, Eriphia smithi, and Ocypode cordimana, from Jejudo Island are recorded for the first time in Korea. M. orientalis was collected under the rocks by SCUBA diving in 20m and at low tidal mark. However, E. smithi and O. cordimana were collected in crevices of the rock at low tidal mark and in a burrow of sand beach at supra tidal mark, respectively. At present, E. smithi is the only species of the genus represented in Korean waters. Including the new records in this study, the established brachyuran fauna in Korea now comprises 203 species.

A taxonomic study for clarifying the decapod fauna of Gejedo Island, Korea was performed. Seventy nine species in 28 families were identified through the present investigation and of which 9 species of shrimps, 7 species of anomurans, and 39 species of crabs are newly added to the decapod fauna of this area. With the previously known 40 species, a total of 93 decapod species from this island and its adjacent islets are listed, and Pugettia quadridens intermedia Sakai, 1939 is redescribed with illustrations. The zoogeographical aspects of Geojedo Island are also discussed based on the composition of geographical forms of brachyuran decapods.

The leucosiid crabs are common species on soft sediment from the intertidal flat to shelf and slope depths. The genus Nursia Leach, 1817 is characterized by the pentagonal shape of the carapace and the presence of the buccal cavern on the pterygostomian region. As a result of the systematic study on the Korean brachyuran species, Nursia rhomboidalis (Miers, 1879) is newly recorded in Korean fauna. Korean Leucosiidae is now composed of 14 species belonging to eight genera. The description and illustrations of this species are provided.

We examined the effect of predation by observing the changes in macrobenthic communities in a tidal flat at Seonjae, Korea, following the exclusion of large predators such as birds, fishes and crustaceans using protective screens. We conducted two interference experiments in the field from April to November 2004: (1) Experiment 1 was conducted at a mid-tidal flat in the western part of Seonjae-do, Incheon, Korea, (2) Experiment 2 was set up at a low tidal flat in the eastern part of Seonjae-do. predator exclusion showed different effects in the two experiments. Both the number of species and density were reduced by 20% in Experiment 1. Whereas in Experiment 2, they increased by up to 13% and 69%, respectively. In Experiment 1, a high density of brachyuran crabs observed in the treatment may have caused the difference in community composition between the treatment and the control, and this probably resulted from active predation of macrofauna (e.g., small crabs) under protection from megafaunal predators such as birds and fishes. However, in Experiment 2, as typically observed in other predator exclusion experiments, a lower density of benthic predators and the subsequent reduction of over predation probably resulted in a more diverse and abundant benthic community in the treatment. We confirmed that predation was a contributing factor in the formation of the macrobenthic community. We also demonstrated relationships that exist among different trophic groups (large predators, macrobenthic predators and prey) and what effects and responses occur in each component of the tidal flats.

We studied the ectosymbionts associating with the sea anemone Stichodactyla gigantea at Kosrae, Micronesia. Ectosymbionts of seven species associated with 60.7% of S. gigantea (n=28), with a mean of 2.4 per anemone and 3.9 per occupied anemone. Anemones hosting one or more ectosymbionts did not differ significantly in size from anemones lacking ectosymbionts and there was no significant correlation between anemone size and the number of ectosymbionts. Of 67 ectosymbionts observed, the sea cucumber Stichopus vastus comprised 23.9%, followed by the shrimp Thor amboinensis (20.9%), unidentified hermit crabs (Paguroidea; 20.9%), the cardinalfish Ostorhinchus novemfasciatus (20.9%), the shrimp Periclimenes brevicarpalis (9.0%), the sea cucumber Holothuria hilla (3.0%), and an unidentified brachyuran crab (1.5%). This study documents the first records of S. vastus, H. hilla, and O. novemfasciatus associating with S. gigantea, and the first locality records of S. gigantea, T. amboinensis, P. brevicarpalis, and S. vastus for Kosrae. Because humans often harvest S. gigantea for food at Kosrae, we recommend protecting the symbiotic assemblage of S. gigantea by establishing a sustainable system of harvesting.
