Meiobenthos is a term usually referring to microscopic benthic organisms which pass through a 1 mm mesh sieve and are retained on a 32–63 μm one. Meiobenthos occurs in any aquatic environment, shows high species diversity as well as high biomass, and often plays an important role in ecological and evolutionary studies. However, the species diversity of these animals in Japanese waters has been insufficiently investigated. Here we review several methodologies for collecting extant meiobenthos from the marine environment, including the method for sampling sediments in various environments, extracting meiobenthos from the sediment samples, and some tips for sorting, fixation, and observation of them.

Tardigrades are microscopic invertebrates comprising Panarthropoda with two other phyla, Arthropoda and Onychophora. More than one thousand tardigrade species are known worldwide from marine, freshwater, and limno-terrestrial environments. To facilitate beginners interested in tardigrade systematics, the collection methods for these three environments, the specimen preparation methods for light microscopy and scanning electron microscopy, the DNA extraction procedures, and the recent advances in the systematics of the four orders belonging to the two classes, Eutardigrada (Apochela and Parachela) and Heterotardigrada (Arthrotardigrada and Echiniscoidea), are reviewed. The present status of the Japanese tardigrade fauna is also mentioned in brief.

In this study, we had investigated the benthic deep-sea fauna using the dredge and beam trawl in the region from the continental shelf to the continental slope of the Sea of Kumano, Mie Prefecture, during the No.1722 research voyage of the training ship Seisui-Maru of Mie University. The survey was carried out at 16 stations covering a depth range of 113-1059 m. The results of the survey, 14 phyla had been confirmed. Arthropod, echinoderm, annelid and molluscan macrobenthos were collected from all of the stations. The phylum number of each station was in the range from 4 to 11. The largest number of phyla had been confi rmed at St.10D of boulders bottom(768-800 m depth). Meiobenthos confi rmed in our sample were kinorhynchs, nematodes, tardigrades, loriciferans and small arthropods such as tanaidaceans, copepods and cumaceans. In addition to free-living species, parasitic copepods, isopods, platyhelminthes, acanthocephalans and nematodes had been found in fish, crustaceans and polychaetes.
