A male Aetobatus narinari (978.1 mm in DW) was collected from Enoshima on June 30, 2016. This specimen represents the northernmost record of the species and its first record from Sagami Bay. We inferred that the species entered Sagami Bay because of a slight difference in water temperature between the bay and the Kuroshio Current at that time.
