The distribution of the genus
Eleotris (Gobioidei: Eleotridae) in Kanagawa Prefecture, Japan, was investigated on the basis of the literature, museum collections and field work in rivers. Four species,
i.e. Eleotris acanthopoma,
E. fusca,
E. melanosoma and
E. oxycephala, were identified in the region. They were recorded mainly from the rivers along Sagami Bay, which is strongly influenced by the Kuroshio Current. The species occurred in rivers along Tokyo Bay but it is thought that only
E. oxycephala winters in the prefecture. The vast majority of specimens of the other three species were juveniles, and this suggests that these species have not established viable populations in the region.
E. fusca is recorded from the prefecture for the first time, representing the northernmost record of the species.
