Cinusa nippon Nagasawa(Isopoda: Cymothoidae), a marine parasite infesting the buccal cavities of coastal puffers, is newly recorded from the Pacific coasts of central Japan. A pair consisting of a mature female and mature male, and six mancae and a juvenile, were collected from reared vermiculated puffer, Takifugu snyderi(Abe)(Tetraodontiformes: Tetraodontidae), in an aquarium and a museum, respectively. The present paper provides a description of the morphological characters of these cymothoids, including their immature stages, and molecular analysis using 16S rRNA for C. nippon and related species. In the maximum likelihood phylogenetic tree, C. nippon was included in the clade of Ceratothoa Dana and corresponds to Ceratothoa sp. 2 reported in another study. These suggest that the relationship between Cinusa Schioedte and Meinert and Ceratothoa needs to be re-examined. Furthermore, the morphological study showed that these cymothoid mancae are similar to Manca type 2 known from zoo-plankton, provided in one of our previous reports.

Toba Aquarium regularly collects marine invertebrates from the Kumano Sea on the Pacific coast of central Japan. These animals are mainly used for exhibition in the aquarium as well as for taxonomic studies. When the taxonomic status of the animals is uncertain, we work with researchers to observe the specimens of those marine invertebrates. From 2006 to 2019, 382 species from 12 phyla have been so far recorded from the bathyal zone of Kumano Sea. Together with 26 researchers, we examined a total of 103 species collected during the surveys and nine out of them were described as new species. Using our rearing techniques, some interesting behaviors of the bathyal marine invertebrates were observed with live specimens in the aquarium.
