Toba Aquarium regularly collects marine invertebrates from the Kumano Sea on the Pacific coast of central Japan. These animals are mainly used for exhibition in the aquarium as well as for taxonomic studies. When the taxonomic status of the animals is uncertain, we work with researchers to observe the specimens of those marine invertebrates. From 2006 to 2019, 382 species from 12 phyla have been so far recorded from the bathyal zone of Kumano Sea. Together with 26 researchers, we examined a total of 103 species collected during the surveys and nine out of them were described as new species. Using our rearing techniques, some interesting behaviors of the bathyal marine invertebrates were observed with live specimens in the aquarium.

<p>Two specimens (67.5–75.1 mm standard length; SL) of <i>Plectranthias maekawa</i> Wada, Senou and Motomura 2018 (Serranidae: Anthiadinae), previously recorded only the Tokara Islands, Kagoshima Prefecture, Japan, were collected from Okinawa-jima and Yonaguni-jima islands, Okinawa Prefecture, Japan. The present specimens, described herein in detail, represent the first records of the species from Okinawa Prefecture. Although the body depth (% of SL) has been regarded as one of diagnostic characters between <i>P</i>. <i>maekawa</i> and two closely-related congeners (<i>Plectranthias helenae</i> Randall, 1980 and <i>Plectranthias wheeleri</i> Randall, 1980) in the original description of <i>P</i>. <i>maekawa</i>, that of the present new specimens was overlapped with the latter two species (viz., 33.5–37.7% of SL in <i>P</i>. <i>maekawa</i>, 35.5–38.7% SL in <i>P</i>. <i>helenae</i>, and 35.6–37.9% of SL in <i>P</i>. <i>wheeleri</i>). The number of serration on the margins of subopercle and interopercle in <i>P</i>. <i>wheeleri</i> and <i>P</i>. <i>maekawa</i> has also been regarded as a diagnostic character for the two species, but additional specimens described in this study showed that the number of serration changed ontogenetically, and it overlapped in the similar-sized specimens of the two species. However, the validities of other diagnostic characters given in the original description of <i>P</i>. <i>maekawa</i> are reconfirmed in this study (viz., number of pectoral-fin rays, scales on above and below lateral line, morphometrics of body width, head length, third dorsal-fin spine length, caudal-peduncle length and depth, and both coloration of fresh and preserved conditions). In addition, three specimens of <i>P</i>. <i>wheeleri</i> (71.3–83.7 mm SL) from the Okinawa Islands, are reported here as the first records of the species from Okinawa Prefecture; it has been previously recorded from Japan (Sagami Bay, and Tokara and Amami islands), Taiwan, Indonesia, and Australasia.</p>

A single specimen of a carangid fish, Alepes kleinii (125.1mm in standard length), was collected by a small set net at depths shallower than 8m off the northeastern Kadogawa Bay, Kadogawa-cho, Miyazaki Prefecture, Pacific coast of Kyushu Island, Japan. Alepes kleinii is distinguishable from its congeners by the following combination of characters: two rows of small conical teeth arranged irregularly in a narrow band on upper jaw but those on lower jaw in a single series, a diffuse dusky blotch present on upper margin of opercle, and straight part of lateral line starting behind below origin of second dorsal fin. The specimen represents the reliable record of the species from Japan.

Two yellowish damselfishes (Perciformes: Pomacentridae), Chromis analis (Cuvier in Cuvier and Valenciennes, 1830) and C. xouthos Allen and Erdmann, 2005, were confirmed to be distributed in Japanese waters on the basis of collected specimens and underwater photographs. Detailed comparisons of the two species are given in this study, with assessments of standard Japanese names for the two. New standard Japanese name, “Tampopo-suzumedai”, is herein proposed for C. analis.

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.

An overview of "scorpaeniform" fish phylogenetic studies is presented. Imamura and Shinohara (1998) reviewed previous phylogenetic studies of the "Scorpaeniformes" and stated that monophyly was unlikely. Since 1998, 4 papers (1 morphological and 3 molecular) have been published, which independently show the polyphyletic origins of this group. The present paper provides an outline of Imamura and Shinohara's (1998) paper, and gives summaries of the 4 subsequent papers. Evidence for polyphyly presented in the 4 papers is discussed. Suggestions for future areas of "scorpaeniform" taxonomic and evolutionary research are presented.

Ten carangid specimens belonging to the genus Selar, collected by small set net at Kadogawa Bay, Miyazaki Prefecture (eastern coast of Kyushu Island), Japan, were identified as Selar boops (Cuvier in Cuvier and Valenciennes, 1833), on the basis of scales in curved part of lateral line 22-24 and chord of the curved part of lateral line 2.2-2.7 times in straight part. These specimens represent first record of the species from Japan. Specimens are described and a new Japanese name "Teru-meaji" is proposed for the species.

The scale worm Hesperonoe hwanghaiensis Uschakov and Wu, 1959 (Annelida: Polynoidae) is recorded from eastern Japan, based on four specimens collected from Akkeshi Bay, Hokkaido, and Kashima-nada, Ibaraki Prefecture. In Akkeshi Bay, three specimens (body length of a complete specimen: 40 mm, body width without parapodia: 4.0–4.5 mm), which are the largest of all Japanese specimens including previous records, were found from mud and sand sediments at intertidal flats, where a mud shrimp Upogebia major (De Haan, 1841) was collected simultaneously. In Kashima-nada, a complete mature male specimen (body length: 23 mm, body width without parapodia: 2.7 mm) was collected by dredging at subtidal sandy bottom at a water depth of 7.6 m, where another mud shrimp Austinogebia narutensis (Sakai, 1986) was collected simultaneously. The morphological characteristics of these specimens basically agreed with those of the previous records on the specimens collected from western Japan, with a diagnostic characteristic of the presence of a row of the more conical macrotubercles (up to 28 in an elytron of the complete specimen from Akkeshi Bay, and up to 3 in that from Kashima-nada) on the posterior surface of the elytra in the larger specimen. The present result suggests that the scale worm is commensal with not only U. major but also A. narutensis in its habitats extending from intertidal flats in semi-enclosed inner bays to subtidal bottom in open coasts.

<p>In the submarine caves of the Ryukyu Islands, the existence of many non-described species has been indicated in field surveys. To estimate the magnitude of biodiversity in the submarine caves, application of genetic analyses would provide a promising approach. Genetic analysis by DNA barcoding based on mitochondrial cytochrome c oxidase subunit I (COI) is informative for the study of submarine caves because the data of COI region have been accumulated in many marine animals. Also, in order to understand the formation process of communities of submarine caves, population genetic approaches would be useful to evaluate the connectivity patterns among submarine caves which are not continuously distributed along the Ryukyu Islands. In addition, utilization of high-throughput sequencing technology (e.g., environmental DNA (eDNA) analysis) would be also powerful for the ecological studies of submarine caves of the Ryukyu Islands. We discuss the current situation of genetic analyses in the submarine caves of the Ryukyu Islands and propose the prospects of genetic analyses for future studies.</p>

This paper provides a review of the past progress and future potential for research on the decapod crustacean fauna in submarine caves of the Ryukyu Islands. Until now, approximately 66 decapod crustacean species (shrimps, lobsters, and anomuran and brachyuran crabs) have been recorded from such caves at six islands in this chain, but recent surveys suggest that up to 100 species may be present. Many of them, however, appear to be accidental intruders or nocturnally emergent species, whereas “cavernicolous” species (animals that have characteristic morphological features such as reduced eyes and/or elongate thoracic limbs and spend their entire adult lives in the caves) are not so common. In addition, recent surveys have shown that the factors determining the distributional pattern of cavernicolous decapods among caves and their ecological partitioning within caves may be influenced by cave morphology and various aspects of the interior environment (light conditions, salinity, substratum, etc.). The urgency of preserving submarine cave environments in the Ryukyu Islands in the face of various threats is emphasized. In particular, 16 species of cavernicolous decapods found in submarine caves are already currently listed in the “Red List of Threatened Marine Species” issued by the Ministry of the Environment, Government of Japan.

Submarine caves are widely known for their unique biodiversity and peculiar ecosystem. In the submarine caves around the Ryukyu Islands, sponges are the most abundant and diverse organisms. These sponges are considered to play an important role for the coral reef ecosystem in terms of supplying food resources to other organisms. An overview of the features of submarine cave sponge fauna especially at the “Akuma-no-Yakata” cave in Shimoji Island, Miyako Islands, Okinawa is presented herein. Sponges in “Akuma-no-Yakata” are roughly categorized into three types based on their distribution pattern inside the cave. The first category is sponges living around entrance of the cave, which are conspecific with species attached on underside of overhangs and interstices of coral reef. These species are considered as species just favoring cryptic habitats. The second category is sponges living around the mid part of the cave, some of which are closely related to species found in the deep-sea fauna. Lastly, the third category is sponges living in innermost part of the cave, which possibly have strong tolerance to low salinity water. The environment of second and third category is affected by fresh water infiltrated through calcareous ground of the island, and can be regarded as anchialine habitat, where the sponge fauna is very unique.

Recent taxonomic studies on Peracarida in submarine and anchialine caves of the Ryukyu Islands were reviewed. Peracarida is a large suborder of malacostracan crustaceans including more than 24,000 species known form marine, brackish, fresh water and terrestrial habitats. They are defined by the presence of a brood pouch. A total of 9 species, belonging to 7 genera of 7 families have been recorded in submarine and anchialine caves of the Ryukyu Islands.
