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.

Auricularia specimens deposited in the National Museum of Nature and Science, Japan, were observed to reexamine their species identification based on updated taxonomic criteria, and to verify the taxonomy and distribution of Auricularia spp. in Japan. Four of the ten specimens previously identified as A. auriculajudae were reidentified as A. americana (1), A. cornea (1), and A. villosula (2) based on morphological criteria such as medullae, abhymenial hairs, and basidiospores. The remaining six specimens could not be identified at the species level due to the lack of distinguishing morphological characteristics. Two of the five specimens previously considered A. minor were identified as different species due to basidiospore size discrepancy, but the remaining two specimens and the type specimen were in poor condition, and their basidiospores could not be properly observed. Three of the nine specimens previously identified as A. polytricha were reidentified as A. cornea based on morphological criteria. The remaining six specimens were not identified as A. polytricha. The type specimens of A. polytricha f. leucochroma and A. polytricha f. tenuis were in poor condition, and their basidiospores could not be properly observed. Reexaminations of existing specimens based on recent taxonomic criteria will contribute to updating the taxonomy and distribution of Auricularia spp. in Japan.

In this study, we aimed at clarifying the recent trends in narrow-ridged finless porpoise stranding on the west coast of Ise Bay. We analyzed the annual/monthly change in the number of stranded individuals, the status found, the length and sex of the individuals, and the seasonality of the geographical distribution data from 486 individuals collected along the northern central coast of Mie Prefecture for 10 years from January 2011 to December 2020. The annual number of stranded individuals fluctuated between 2011 and 2015, although it was stably around 60 individuals after 2016 when a local stranding network of universities, aquariums, museums, and local governments were established. As for the status of stranding, 96.5% of the individuals were found alone and they were dead except one. More males were observed among the stranded individuals than females with a sex ratio of 1.4. The body length frequency data showed that 75-85 cm individuals, approximately of birth length, accounted for 51.1% and 39.1% in the male and female groups, respectively, and stranding during the newborn period was overwhelmingly predominant. Several individuals below the birth length were found in April-July while the peak of calving season was considered to be April-June. The monthly number of stranded individuals peaked in May-June every year, and dead newborn calves were major factors in boosting the number of stranded individuals found during this period. The geographical distribution of stranded individuals displayed seasonal changes. Most stranded animals were recorded in the central part of the west coast of Ise Bay in April-June, exhibiting a gradual decrease and becoming scarce by January-March.

Annotated checklist of marine and fresh water fishes is reported from the Hyuga Nada area, including Miyazaki Prefecture, southern coastal area of Oita Prefecture and eastern coast of Kagoshima Prefecture, southwestern Japan. Such fishes are classified into 228 families, 680 genera and 1,340 species including 24 subspecies and 1 hybrid, consisting of natural inhabitants in the area, and invasive and introduced fishes as alien species out of Japan or from the other areas. Confirmation of each species on identification is based on voucher specimens kept in Miyazaki University and other museums, photographs of fishes taken in the area, confirmed photographs in websites and references formerly reported before August 2016. Fish occurrence tendency by our gross observation is noted at each species.
