What kind of animal is a dolphin that belongs to the river dolphin family? We will explain its long length, body, characteristics, distribution, ecology, habitat, and types. These include the Ganges river dolphin and the Indus river dolphin, both of which are designated as endangered species, so they are in a very critical situation. Therefore, I will explain in detail.

Both the Ganges river dolphin and the Indus river dolphin are in decline in population and are designated as endangered species. I will explain the reasons for each. It has been listed in CITES Appendix I since 1975, when CITES came into force.
ganges river dolphin
Since 1981, the genus Ganges River Dolphin has been listed in Appendix I of CITES. Their population is drastically decreasing due to habitat fragmentation, water pollution, and even capture.
