| Summary: | In Japan, the chinese finless porpoises which had been caught in the Japanese coastal sea are bred in three aquariums, but the underwater sound of this species have not been recognized yet. The authors collected their signals and analyzed them by sound spectorograph in the same way as for the bottlenosed dolphin. 1) Unlike the bottlenosed dolphin, however, this species did not make "Whistle", and "Clicks" of this species were lower than those of the bottlenosed dolphin. |
