- Co-Occurrence of Gastropods of the Genus (Mollusca: Eulimidae) Parasitizing the Black Sea Cucumber in Central Japan: Implications for Their Geographic Distribution and Parasitic Ecology. Nakano, Tomoyuki Nishiyama, Erina Takano, Tsuyoshi Animals Japan Animal Distribution Holothuria Snails of the family Eulimidae are parasites of echinoderms in all five extant classes. Despite long years of taxonomic research on Eulimidae in Japan, their local species richness remains to be investigated, and few studies have focused on a eulimid fauna of a certain echinoderm taxon, even if it is a common species. Here, we conducted a comprehensive sampling of species parasitizing the black sea cucumber in Shirahama, Wakayama, central Japan. The data used in this study were partly obtained during a summer education program of the Seto Marine Biological Laboratory, Kyoto University. and parasitized the external surface, and two unidentified species were found inside the host's body cavity. This study represents the first record of in Japanese waters and eulimids exploiting the internal habitat of . Morphological and molecular comparisons between the present four species and other Japanese specimens suggested that they generally exhibit wide geographic distributions and low host specificity. Additionally, the two species from the body cavity were probably seldom observed in central Japan, as inferred from the accumulated results of the dissection of through a long-running, annual education program at Shirahama.
