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.
