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.

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.

Paleontologists have long reconstructed phylogeny using comparisons between fossil record and recent taxa. On the other hand, biologists reconstruct phylogeny using molecules to produce a tree which they constrain using fossils and geographic events to provide estimates for phylogenetic events. Taking both extant and extinct species into account for systematic revisions is essential for biologists and paleontologists. In this paper, I demonstrate example of how paleontological methods, such as preparing thin sections and using x-ray and CT scans can also be applied to extant invertebrates. I provide further discussion of how robust integration between paleontologists and biologists is rewarding to both disciplines.

The order Euryalida Lamarck, 1816 (Echinodermata: Ophiuroidea) comprises 4 families, 48 genera and about 190 species and is known from marine water. By the examination of type specimens of 117 species, taxonomy of euryalid genera and species from the Western Pacific are revised. With junior synonymizations of 2 species and descriptions of 1 genus and 5 species, a total of 120 species were recognized in this region. Molecular phylogeny based on mitochondrial and nuclear genes reviewed family-level systematics of the order.

Ophiuroidea is the largest class of echinoderms and can be found in a great variety of marine habitats such as: in interstices in sponges and hard corals; on muddy ground; infaunally buried in sediments; under rocks; and on the surfaces of various animals such as soft corals. Very few species, however, have been recorded from submarine caves and only one anchialine endemic species, Amphicutis stygobita Pomory, Carpenter & Winter, 2011 is known from Bernier Cave, Bahamas, and three undescribed species were inferred by molecular phylogenetic analysis based on the specimens collected from Mexico. During the course of benthic faunal surveys in three submarine caves of the Ryukyu Islands, southwestern Japan, at 2016 to 2018, 19 ophiuroid species in of 13 genera from 8 families were recorded.
