    <title>Abstract</title>Terebellidae worms have large numbers of tentacles responsible for various biological functions. Some Terebellidae worms whose tentacles emit light are found around the world, including exceptional violet-light-emitting <italic>Polycirrus</italic> spp. found in Europe and North America. However, there is no video-recorded observation of the luminous behavior of such unique species in nature, and the genetic information related to their ecology are lacking. Here, for the first time, we video-recorded the violet-light-emitting behavior of an undescribed Japanese worm in its natural habitat. The worm was designated as <italic>Polycirrus</italic> sp. ISK based on morphological observations, and the luminescence spectrum showed a peak at 444 nm, which is an exceptionally short wavelength for bioluminescence in a shallow coastal water environment. An analysis of differentially expressing genes based on separate RNA-Seq analysis for the tentacles and the rest of body revealed the specific expression of genes that are probably involved in innate immunity in the tentacles exposed to predators. We also found a <italic>Renilla</italic> luciferase homologous gene, but coelenterazine was not detected in the worm extract by analyses using a liquid chromatography and a recombinant <italic>Renilla</italic> luciferase. These results will promote an understanding of the ecology and luminescence mechanisms of luminous <italic>Polycirrus</italic> spp.

    <title>Abstract</title>
    Pelagic polychaetes are distributed from the sea surface to greater depths of the oceans worldwide, but little information is available regarding their ecology. This study investigated the vertical distribution of abundance, biomass and community structure of pelagic polychaetes at a single station in the western subarctic Pacific based on day–night vertical stratified samples collected from a 0 to 1000 m water column during four seasons covering 1 year. The polychaete abundance and biomass ranged from 0 to 757 ind. 1000 m−3 and 0–6.1 mg WW m−3, respectively. Ten pelagic polychaete species belonging to nine genera and six families were identified. From cluster analysis based on abundance, the polychaete community was divided into five communities. Each community occurred at different depth layers. Two surface groups seen at 0–200 m were dominated by two carnivorous species: Tomopteris septentrionalis and Typhloscolex muelleri. The deepest group, dominated by the particle feeder Pelagobia longicirrata, was seen at 500–1000 m. Two transition groups occurred in the intermediate depths. These vertical distributions of the pelagic polychaete communities were common throughout the season and day. Water mass, food availability and the oxygen minimum layer are put forth as environmental factors that affect the pelagic polychaete community.

    In Australia, the deep-water (bathyal and abyssal) benthic invertebrate fauna is poorly known in comparison with that of shallow (subtidal and shelf) habitats. Benthic fauna from the deep eastern Australian margin was sampled systematically for the first time during 2017 RV ‘Investigator’ voyage ‘Sampling the Abyss’. Box core, Brenke sledge, and beam trawl samples were collected at one-degree intervals from Tasmania, 42°S, to southern Queensland, 24°S, from 900 to 4800 m depth. Annelids collected were identified by taxonomic experts on individual families around the world. A complete list of all identified species is presented, accompanied with brief morphological diagnoses, taxonomic remarks, and colour images. A total of more than 6000 annelid specimens consisting of 50 families (47 Polychaeta, one Echiura, two Sipuncula) and 214 species were recovered. Twenty-seven species were given valid names, 45 were assigned the qualifier cf., 87 the qualifier sp., and 55 species were considered new to science. Geographical ranges of 16 morphospecies extended along the eastern Australian margin to the Great Australian Bight, South Australia; however, these ranges need to be confirmed with genetic data. This work providing critical baseline biodiversity data on an important group of benthic invertebrates from a virtually unknown region of the world’s ocean will act as a springboard for future taxonomic and biogeographic studies in the area.

    <title>Abstract</title>The phylum Annelida exhibits high morphological diversity coupled with its extensive ecological diversity, and the process of its evolution has been an attractive research subject for many researchers. Its representatives are also extensively studied in fields of ecology and developmental biology and important in many other biology related disciplines. The study of biomineralisation is one of them. Some annelid groups are well known to form calcified tubes but other forms of biomineralisation are also known. Herein, we report a new interstitial annelid species with black spicules, <italic>Thoracophelia minuta</italic> sp. nov., from Yoichi, Hokkaido, Japan. Spicules are minute calcium carbonate inclusions found across the body and in this new species, numerous black rod-like inclusions of calcium-rich composition are distributed in the coelomic cavity. The new species can be distinguished from other known species of the genus by these conspicuous spicules, shape of branchiae and body formula. Further, the new species’ body size is apparently smaller than its congeners. Based on our molecular phylogenetic analysis using 18S and 28S sequences, we discuss the evolutionary significance of the new species’ spicules and also the species' progenetic origin.

    Among ~1300 species of world nemerteans, seven species in five genera of lineid heteronemerteans have been known to possess a branched proboscis. In this paper, we describe the eighth branched-proboscis species: Gorgonorhynchus citrinus sp. nov. from Okinawa, Japan. We also report Gorgonorhynchus cf. repens Dakin &amp;amp; Fordham, 1931 with uniformly orange body, as a new member for the Japanese nemertean fauna. We infer the phylogenetic relationships between these forms and other members of Lineidae McIntosh, 1874 for which partial sequences of the mitochondrial 16S rRNA and cytochrome c oxidase subunit I, and the nuclear 18S rRNA, 28S rRNA, and histone H3 genes are available in public databases, along with newly sequenced data of another branched-proboscis heteronemertean, Polydendrorhynchus zhanjiangensis (Yin &amp;amp; Zheng, 1984) from China. In the resulting tree, Gorgonorhychus Dakin &amp;amp; Fordham, 1931 was sister group to non-branched-proboscis Dushia Corrêa, 1963, whereas P. zhanjiangensis was sister group to likewise non-branched-proboscis Cerebratulus lacteus (Leidy, 1851).

    A new interstitial acrocirrid, Actaedrilus yanbarensis gen et. sp. nov., is described from Okinawa-jima Island, Japan. Individuals of the new genus and species were collected from the interstices of subtidal coarse sand (about 1 m depth). The new genus is comprised of the new species and A. polyonyx (Eliason, 1962) comb. nov. and it is characterized by the presence of two pairs of long branchiae, non-retractile head, minute body, and short club-shaped palps. We infer the phylogenetic position of A. yanbarensis gen. et sp. nov. within Acrocirridae using five gene markers (COI, 16S, 18S, 28S, Cyt B).

    Community structure and seasonal changes in the population structure of pelagic polychaetes were studied based on zooplankton samples collected by sediment traps moored at 200 m depth in the subarctic and subtropical western North Pacific throughout the year. Eight species belonging to seven genera and seven families occurred at the subarctic station, while twelve species belonging to ten genera and seven families were identified at the subtropical station. Polychaete abundance was 5.37 ± 0.44 ind. m-2 day-1 (annual mean ± standard error) at the subarctic station, and 1.36 ± 0.15 ind. m-2 day-1 at the subtropical station. Polychaete abundance at the subarctic station was high from May to August, but no seasonal patterns were observed at the subtropical station. The dominant species in the subarctic was Tomopteris septentrionalis, which accounted for 62.9% of annual mean abundance; at the subtropical station, the dominant species was Pelagobia sp. (22.8%). In the subarctic, small specimens of T. septentrionalis (&lt;3 mm in body length) occurred only in winter (December-March). No clear seasonal changes in population structure of the subtropical Pelagobia sp. were detected. The latitudinal patterns we observed in the polychaete communities of the western North Pacific were similar to those previously observed in the eastern North Pacific. Changes in the population structure of T. septentrionalis suggest that the life cycle of this species is seasonal in the subarctic region.

    We describe a new species of polyclad flatworm, Pericelis flavomarginata sp. nov., from the intertidal and subtidal zones along localities on the Pacific coast of Japan. Pericelis flavomarginata sp. nov. is characterized by i) the dorsal surface of the body fringed by a lemon-yellow line except for the tip of tentacles, with a narrow brown midline running from the anterior edge of the body to the posterior end of the pharynx, ii) the pair of marginal tentacles with the tips extending and tapering, and iii) the presence of a common gonopore. Our molecular phylogenetic analysis revealed that selected Pericelis species were divided into two clades, each of which may be agreed with a characteristic dorsal color pattern. Additionally, we report an observation on the feeding behavior of P. flavomarginata sp. nov. on the polychaete Iphione muricata (Savigny in Lamarck, 1818).

    Lacydonia japonica sp. nov. (Annelida, Lacydoniidae) is described based on material found in sediments collected off the Pacific coast of northern Honshu, Japan, at depths of 262 m and 407 m. The sediments were obtained by a remotely operated vehicle equipped with a suction sampler during a Tohoku Ecosystem-Associated Marine Sciences (TEAMS) project in 2019. Lacydonia japonica sp. nov. belongs to the eyeless group of lacydoniids and is discriminated from the morphologically most similar congener, Lacydonia papillata Uschakov, 1958 by its reddish pigments on both the dorsal and ventral parapodial cirri and four pigment spots on the pygidium. To assess the phylogenetic position of the new species among other lacydoniids for which sequence data are available in public databases, analyses were performed using the mitochondrial cytochrome c oxidase subunit I (COI) and 16S rRNA, as well as the nuclear 18S rRNA and 28S rRNA genes. We additionally obtained some lacydoniids by sledging off western Japan, but these were severely fragmented and broken during collection. Using the paucity of morphological data, they were left unidentified as Lacydonia sp. but included in the molecular analyses. Genetic distances between Lacydonia eliasoni Hartmann-Schröder, 1996, Lacydonia japonica, and Lacydonia sp. off western Japan were 10.4-17.1% uncorrected p-distance (11.3-18.6% K2P) in terms of 658-bp COI sequences.

    Preliminary results of the deep-sea faunal survey conducted from the TR/V Seisui-maru of Mie University in April 2019 are presented. A total of 20 taxonomists and ecologists working on a wide variety of animal taxa participated in this survey. Surveyed areas included the Kumano Sea(off Mie Prefecture)and south of the Kii Strait(off Tanabe Bay, Wakayama Prefecture), at depths of 112-775 m. Sampling gears employed were beam trawl and biological dredge. The collection is represented by macrobenthos and meiobenthos from nine animal phyla, including echinoderms, arthropods, molluscans and annelids. The number of phyla occurring in each station varied from seven to eight. The station with most diverse fauna at the phylum level was St. 3B(south of the Kii Strait, 775-661 m depth, mud bottom).Meiofauna includes priapulids, nematodes and small arthropods such as copepods, tanaidaceans, amphipods, isopods and cumaceans. In addition to freeliving species, cnidarians symbiotic on a gastropod and an antipatharian, and crustaceans parasitic on a fi sh and sea urchins were also collected. Preliminary identifi cations are given for Asteroidea, Ophiuroidea, Holothuroidea, Crinoidea, Cyclopoida, Siphonostomatoida, Tanaidacea, Isopoda, Decapoda, Mollusca, polychaetes, Bryozoa, Cnidaria and Nemertea.

    Terebelliformia is a benthic group of marine annelid worms. The bioluminescence of several species has been reported in taxonomical and histological literature, but very little information is known about the biochemical aspects of this phenomenon. In this study, we examined the basic properties of the luminescence system using an extract of the Japanese terebelliform worm, Thelepus japonicus. The bioluminescence extract was soluble in water, and emitted blue-green light at λmax 508 nm following the addition of divalent cations. This triggering action was highly specific to Fe2+ and addition of ATP, H2 O2 or coelenterazine did not enhance activity. The bioluminescence was inactivated by heat treatment and organic solvents, indicating the involvement of a protein component. These results suggested that Thelepus worm produces light using a novel system that differs from that in other known luminescent annelids.

    In this study, we had investigated the benthic deep-sea fauna using the dredge and beam trawl in the region from the continental shelf to the continental slope of the Sea of Kumano, Mie Prefecture, during the No.1722 research voyage of the training ship Seisui-Maru of Mie University. The survey was carried out at 16 stations covering a depth range of 113-1059 m. The results of the survey, 14 phyla had been confirmed. Arthropod, echinoderm, annelid and molluscan macrobenthos were collected from all of the stations. The phylum number of each station was in the range from 4 to 11. The largest number of phyla had been confi rmed at St.10D of boulders bottom(768-800 m depth). Meiobenthos confi rmed in our sample were kinorhynchs, nematodes, tardigrades, loriciferans and small arthropods such as tanaidaceans, copepods and cumaceans. In addition to free-living species, parasitic copepods, isopods, platyhelminthes, acanthocephalans and nematodes had been found in fish, crustaceans and polychaetes.

    Elisesione imajimai sp. nov. is newly described based on specimens collected in Sagami Bay, Japan, at a depth of 150-250 m. This new species resembles E. problematica (Wesenberg-Lund, 1950) from Iceland, but differs because in E. imajimai sp. nov. the ventral cirri surpass the tips of the neurochaetal lobes, reaching to the medial part of the neurochaetal bundle
    the palps are 1/2 – 4/5 as long as the antennae
    the aciculae are pale brownish
    and the dorsal integument shows 9-10 transverse wrinkles per segment, whereas in E. problematica the ventral cirri hardly reach the tips of the neurochaetal lobes
    the palps are as long as the antennae
    the aciculae are black
    and there are 15 transverse wrinkles per segment. A morphological redescription of E. problematica based on its type material and a revised key to identify species in the genus are also provided. A phylogenetic analysis based upon four genes (COI, 16S, 18S, 28S) confirms its position within Hesionini.

    The hesionid polychaete Hesione reticulata von Marenzeller, 1879 was described from Enoshima Island, Japan and has been recorded also from the Red Sea. Depending on researchers, it has been regarded as either a distinct species or synonymous with older established ones. The type specimen has been lost. In order to clarify its taxonomic status, H. reticulata is herein redescribed, illustrated, and a neotype is proposed based on recent material collected near the type locality. The diagnostic features include the presence of several dorsal, discontinuous longitudinal bands, interrupted by pale segmental spots; prostomium with tiny antennae; a tuberculated dorsal integument; acicular lobes double; and neurochaetal blades with guards approaching the distal tooth. The dorsal color pattern in life enables a clear distinction from similar species such as H. intertexta Grube, 1878 amongst others. Mitochondrial COI barcoding sequences are deposited in the DNA Data Bank of Japan. A key to Hesione species from Japan is also included.

    Diplocirrus nicolaji is a flabelligerid worm originally described from shallow waters of Peter the Great Bay, Sea of Japan. Later, this species was also recorded from Japan, but detailed data were not provided
    thus the occurrence of D. nicolaji in Japan needs to be confirmed based upon additional material. The collection of 20 D. nicolaji individuals from four localities along Japanese coasts (the Sea of Japan and western Pacific Ocean), allowed us to provide detailed morphological observations using stereoscopic and scanning electron microscopy. Partial cytochrome c oxidase subunit I sequences were obtained for phylogenetic analysis. Although the morphological analysis detected a few variations in palp length and body colour in ethanol among the local populations, the phylogenetic analysis confirmed their conspecificity with little genetic divergence. This is the first report of D. nicolaji from the western Pacific Ocean and extends its distribution southward.

    JAMBIO, Japanese Association for Marine Biology, has been organizing JAMBIO Coastal Organism Joint Surveys at Shimoda Marine Research Center, University of Tsukuba, and Misaki Marine Biological Station, the University of Tokyo. The aims of the Surveys are to uncover the benthic marine fauna of the coastal areas in and around Sagami Bay, and to form a collaborative network between marine biologists across Japan. We have so far performed six surveys, with over 100 participants in total, using common equipment such as dredges, bottom mud samplers, and epibenthic sleds. Even in Sagami Bay, one of the most intensively studied marine environments in the world, we have succeeded in collecting about 50 probable undescribed species. Other species were collected for the first time from Sagami Bay or found from previously unreported depth. The Surveys could be useful for ecological and environmental studies as well. We plan to continue the JAMBIO Coastal Organism Joint Surveys to further reveal the rich biodiversity within and around Sagami Bay and to accelerate nationwide research collaborations. We also hope to expand the Surveys to include plants and protists, and to perform them at other areas in Japan. Through the Surveys, we aim to develop new cross-disciplinary research areas and to record the long-term transition of biota along the Japanese coast. (C) 2015 Elsevier B.V. All rights reserved.

    平成30年度は前年度に引き続き深海域の多毛類のサンプリングを行った。日本各地およびパナマ・アメリカにおいてサンプリングを行った。実行予定であった南西諸島における調査航海に参加し2000 m、5000 mの大深度のサンプルを得ることができた。これらのサンプルについては今後切片標本を作成する予定である。他の得られた標本についても随時観察用切片標本を作成中である。これらの切片を作成後浅海域と深海域での組織構造の比較を行う予定である。
    また、課題遂行の過程で得られた成果であるウロコムシ科・タンザクゴカイ科多毛類の分類・系統学的データを2本の論文として査読付き英文雑誌に公表した。本成果は浅海から4500 mの幅広い水深から採集された個体をもとに行った1新属2新種の記載を含む。特にタンザクゴカイ科の新属新種であるSpathochaeta octopodisは生態的・系統的にも興味深い種であり、今後詳細な議論を行うためにはさらなるOTUおよび遺伝子領域の追加が必要であるため今後の課題としたい。また現在ウジムカシゴカイ科、ウミケムシ科、ボウセキウロコムシ科多毛類の成果を3本の論文として査読付き英文雑誌に投稿中である。これら以外にも未知の属・種が多く採集されており、それらの分類学的および系統学的位置を把握するためには今後も継続した研究が必要である。それら分類学・系統学的成果を今後2本の論文として査読付き英文雑誌に投稿予定である。
    前年度との成果と合わせると多くの日本未記録の属が記録されており、深海域適応進化を解明する上で重要な情報となる深海性多毛類の多様性・系統関係の整理に貢献した。

    We successfully established 59 cultures of microbial eukaryotes in total and taxonomic studies have been conducted using these cultures. For instance, one culture was of Hemistasia phaeocysticola which was originally described as a member of Myzozoa. The phylogenetic analyses newly revealed that H. pheocysticola does not belong to Myzozoa, but to Euglenozoa. Hence, H. pheocysticola was taxonomically transferred into Euglenozoa in the published paper. By the further and continuous taxonomic studies using other cultures, the diversity of eukaryotic microbes will be understood more properly. When it was difficult or impossible to establish the cultures of the target protists, we conducted the taxonomic studies with the isolated cells. We also conducted the study to understand how complex structural mitochondrial genome and genes have been established by analyzing the established cultures during this period.
