Biology

Because of the geography of the bay there is only a small exchange of water from the bay with the sea. Consequently, the marine life in the bay is different from that in the nearby sea. The bay houses a rare species of finless porpoise, which does not leave the bay during its lifetime. Indo-Pacific bottlenose dolphins and common dolphins may migrate into the basin on unclear regularities. Nagasaki Culture Telecasting Corporation. 2016年10月05日

Another special inhabitant – sometimes characterised as a living fossil – is the horseshoe crab species '' Tachypleus tridentatus''. Despite being nearly separated from the sea, and the large cities along its shore, the bay is full of fish. About 60 species of marine animals are fished.
