The biology of Nymphonella tapetis Ohshima, 1927, a pycnogonid endoparasitic on some bivalves, is reviewed. After the first discovery of this species from Hakata Bay, Fukuoka in 1926, there were scattered records of N. tapetis from several places in Japan before 2007, but they were on a small scale. In April 2007, N. tapetis appeared suddenly in the commercial bivalve, Ruditapes philippinarum and several other bivalves on the Banzu Tidal Flat in Tokyo Bay. The spread of the parasite was explosive, and caused a mass mortality of the bivalves in the area. Adults of the pycnogonid live freely on or just under the surface of sandy bottoms, and show nocturnal activity. The hatching larva is a typical protonymphon larva. The larva enters the host bivalve, attaches to various soft parts, and feeds on the body fluid of the host. The number of parasites in one host ranges from one to over 60. At least eight different developmental stages can be distinguished in the parasitic larvae and juveniles. Adults leave the host probably just after the maturation molt. The adult male receives one egg-mass onto his ovigers after each mating, and one male can bear up to seven egg-masses. Several experiments were undertaken to attempt to eradicate or reduce the number of N. tapetis, but no effective method has yet been found. Three species of the genus Nymphonella have been described from Japan, the Mediterranean, and southern Africa. They are very similar in morphology, which leads to potential taxonomic confusion.

Specimens of scyllarine species (Decapoda: Scyllaridae: Scyllarinae) were collected using commercial bottom trawl nets from several sites with 50-100 m depths in the shelf water region of the Enshu-nada sea and Tosa Bay along the Pacific coast of Honshu, central Japan. Of these, Bathyarctus chani Hoithuis, 2002 and B. formosasus (Chan and Yu, 1992) are recorded for the first time from Japan while Eduarctus martensii (Preffer, 1881) and Galearctus timidus (Hoithuis, 1960) are poorly known from Japanese waters previously.

Misaki Marine Biological Station School of Science, The University of Tokyo which is located on the tip of southwestern Miura Peninsula, Kanagawa Pref. have been actively used as a base for research on Zoology for many years in broad fields, such as development biology, cell biology, molecular biology and systematic zoology. Although technical staffs have greatly supported many scientists, their contribution to the research activity almost remains unknown. In this paper, I describe variety of works that technical staffs of MMBS engage, and a part of research work we are performing.

The taxonomy of Japanese moles, genus Mogera, has been confused since the early 1990s, because of the poorly defined type locality of M. wogura and morphological variability within the genus. Genetic research in recent decades has clarified the taxonomic problems of Japanese moles. This paper uses Japanese moles to discuss the importance of karyological study in mammal species recognition. Chromosomal rearrangements are considered likely to have an important role in species diversification of Japanese moles, resulting from postmating isolation mechanisms induced by abnormal meiosis in heterozygotic hybrids. It is well known that recombination leads to gametes with an unbalanced complement of chromosomal segments in inversion or reciprocal translocation heterozygotes. In the case of Japanese moles, four species of Japanese moles, M. etigo, M. imaizumii, M. tokudae and M. wogura, each have a distinct karyotype and/or morphological traits, and are thus considered to be full species endemic to Honshu, Shikoku and Kyushu.

Taxonomy is recognized as an important infrastructure of biodiversity research and nature conservation. However, taxonomy itself has been declining in terms of number of taxonomists and expertise covering various taxonomic groups. The animal taxonomy in Japan is not an exception. How can animal taxonomists improve this situation? This paper provides several suggestions including basic assessments on animal taxonomy in Japan (e.g., number of taxonomists and number of specialists on various animal taxa), making a nation-wide list of animals in Japan, research projects by groups of different specialists covering different animal taxa, and using biodiversity databases to implement new researches on distribution and phylogeography.

General morphology, distribution, classification, ecology and ontogeny extant crinoids are summarized and reviewed, with particular emplasis placed on the stalked crinoids. Japan is located at or near the northernmost limit of distributions of many stalked crinoid species, which are widely distributed in the western Pacific. Sixteen species of stalked crinoids are currently known from Japanese waters. Thus Japan is an excellent place for the biological study of crinoids, and further research and interesting results are expected.

Taxonomy based on skeletal morphology of the scleractinian corals, especially zooxanthellate corals, is problematic because of the limited number of key characters, their plasticity, and possible morphological convergence. Recently several molecular analyses have been conducted, the controversial results of which compared with the morphological taxonomy. These molecular studies contain several problems. This paper briefly reviews the problems of traditional taxonomy and molecular-based phylogeny, and discusses the recent molecular work, mainly molecular analyses of the subfamily Faviina. Phylogenetic relationships based on the molecular analyses of species in the Faviina did not support the present morphological taxonomy, but fit the geographical distribution, suggesting morphological convergence, and the mode of reproduction. Furthermore, it was found in some cases that phylogenetically closely related species share several morphological characters that were used in past studies, but not used in the current taxonomy. In conclusion, this paper proposes one way to utilize both the morphological taxonomy and molecular analyses in the scleractinian corals.

ZooBank is intended as the official registry of Zoological Nomenclature, according to the International Commission on Zoological Nomenclature. Since its launch in 2005, more than 73, 000 records of Nomenclatural Acts, >29, 000 Publications, and >11, 000 Authors have been deposited in ZooBank as of this writing. An explanatory introduction for ZooBank and proposed three scenarios for mandatory registration of names governed by the International Code of Zoological Nomenclature is given in the Japanese language to popularize relevant issues in domestic taxonomic researchers.

The Tantulocarida are small maxillopodan crustaceans ectoparasitic on amphipods, cumaceans, isopods, tanaidaceans, copepods and ostracods. The group consists of five families, 17 genera, and 25 species, two of which have so far been recorded in Japanese waters. Their taxonomy is based mainly on the morphology of their tantulus larvae and, in addition, adult females and males. Recently two life cycles have been discovered in tantulocaridans : parthenogenetic and sexual. The dispersal phases are tantulus larvae and sexual males and females, all of which are non-feeding stages. Host-specificity seems to be relatively low because a single species has been found infesting nine species of copepods in six families and three orders. These parasites may suppress their hosts' ecdysis. Future studies on the Tantulocarida are proposed.

This article reviews our Internet project activities to establish on-line databases of Japanese moths. Though many large on-line databases of moths are available in the world, only a few resources were available in Japan until our projects began. Our projects consist of the following three parts. "An Identification Guide of Japanese Moths Compiled by Everyone" (http://www.jpmoths.org/) is a huge database which stores 12,000 photographs of 3,200 species. "List MJ: A tentative checklist of Japanese moths" (http://listmj.mothprog.com/) is an up-to-date checklist of Japanese moths. "Gaml" (http://www.mothprog.com/moth/gaml) is a mailing-list for exchanging various information concerning taxonomic, ecological and faunastic studies on moths. One of these "Everyone's Handmade Identification Guide…" is a characteristic project. Most of photographs in this database are taken and identified by anonymous collaborators including some researchers. When a contributor posts a moth image on the bulletin board at the website, someone identifies the image and then the webmaster registers the identified image in the database. These projects provide a communication base for all those interested in moths. They are also useful for researchers since the posted images sometimes include remarkable information for them. These projects will contribute to international projects of biodiversity databases. Further information gathering and improving of accuracy of identification are issues in the future.
