Preliminary results of the deep-sea faunal survey conducted from the TR/V Seisui-maru of Mie University in April 2018 are presented. 18 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 80-821 m. Sampling gears employed were beam trawl and biological dredge. The collection is represented by macrobenthos and meiobenthos from 11 animal phyla, including arthropods, echinoderms, annelids and molluscans. The number of phyla occurring in each station varied from 3 to 7. The station with most diverse fauna at the phylum level was St. 3B (south of the Kii Strait, 421-543 m depth, sandy mud bottom). Meiofauna includes priapulids and small arthropods, such as ostracods, tanaidaceans, isopods, cumaceans and acarus. In addition to free-living species, parasitic crustaceans, platyhelminthes, acanthocephalans, annelids and cnidarians were also collected from fishes, ascidians, urchins, holothurians, crustaceans and polychaetes. Preliminary identifications are given for Ostracoda, Cirripedia, Amphipoda, Decapoda, Asteroidea,Ophiuroidea, Holothuroidea, polychaetes, Echiura, Mollusca and Xenoturbellida.

We herein present the results of a survey which assessed the benthic fauna from subtidal to continental shelf depth in the Shirahama area from 2012 to 2016. Our research resulted in the identification of 132 species from 75 families in seven phyla, Cnidaria, Annelida, Tardigrada, Arthropoda, Mollusca, Echinodermata and Chordata. This includes 24 newly recorded species to Shirahama. Two species were also new records for Japanese waters. Furthermore, six undescribed species and five potentially undescribed species were recorded. We provide a selection of relevant photos for future taxonomic studies and monitoring of environmental changes.

Based on specimens from the gill cavities of one Platichthys stellatus individual collected in the Sea of Japan, we investigated the taxonomic status of the enigmatic caligid genus Pseudolepeophtheirus and its type species, Pseudolepeophtheirus longicauda. In a maximum likelihood (ML) tree based on 18S rRNA gene sequences, the sequence from our sample was nested in a well-supported Lepeophtheirus clade, along with the type species, confirming that Pseudolepeophtheirus should be considered a junior synonym of Lepeophtheirus; our morphological data support this synonymy. Although a previous study had synonymized Pseudolepeophtheirus longicauda with Lepeophtheirus parvicruris, we found that the former differs morphologically from the latter in having a short leg-4 exopod, with the articulation between the first and second segments not evident (the shape of the posterior striated membrane on the leg-2 intercoxal sclerite also differs between two species), and detected slight differences in 18S rRNA sequences between two taxa. We thus concluded that this synonymy is invalid, and reinstate Lepeophtheirus longicauda as a valid species. A ML analysis of COI sequences from Pl. stellatus (the host fish for both L. longicauda and L. parvicruris) showed the host species to comprise distinct northwestern- and northeastern-Pacific clades. Lepeophtheirus longicauda is distributed in the northwestern Pacific and L. parvicruris in the northeastern Pacific, indicating co-divergence of the two copepod species with the host lineages.

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.

With more than 40,000 species, Malacostraca is the most diverse crustacean class. Most malacostracans are gonochoristic, but simultaneous hermaphrodites are also known. Tanaidacea is one of two malacostracan orders that includes simultaneously hermaphroditic species; so far, simultaneous hermaphroditism has been confirmed externally and internally in only two tanaidacean species, both in the genus Apseudes (Apseudidae). Here we show, through external and internal morphological observations of fixed specimens, that the apseudid Falsapseudes bowmani is a simultaneous hermaphrodite, making Falsapseudes the second tanaidacean genus in which simultaneous hermaphroditism has been confirmed both externally and internally. In this species, the epistome (a projection on the clypeus) was thick and elongate in large specimens but was thin and spiniform in smaller specimens; the brooding of eggs or embryos was observed only in thin-epistome individuals, although a pair of ovaries was confirmed in both thick- and thin-epistome individuals. This suggests that individuals with a thick epistome may act as males while also retaining the female reproductive organs.
