I think there are about 50 amazon river dolphins left and only a few Chinese river dolphins left. there are other kinds of river dolphins but I don't know how many are living. They are endangered. Well really there are just the pink dolphins left. And they are endangered. There are only like 1200 left in the Amazon River. They are the last surviving river dolphin.

why did the Indus River Valley have to be rebuilt many times.
There are nearly 40 species of dolphins in the world. Each one has its own conservation status, and, for many species of dolphins, there isn't enough data for the IUCN to determine their conservation status. However, there are at least a few endangered dolphins, (IE, the pink river dolphin in the Amazon rainforest and the Ganges and Indus river dolphins in India), and recently the Chinese river dolphin became extinct.
River Indus has 29 tributaries
None
There were rivers, valleys, land and many other characteristics that were in the Indus River Valley
There are numerous species of wild dolphins around the world and there are thousands of them left. But, because of pollution and habitat destruction their numbers are on a downward trend. Some species of dolphins like the Chinese Pink Dolphin or the Indian Ganges Dolphins are critically endangered while there are some other species whose numbers are quite stable. But still, pollution and loss of habitat is greatly endangering these beautiful creatures.
