The dolphin species in
danger of extinction are the Indus river dolphin, which is
a blind dolphin very small which live in the main river of
Pakistan, the Indus.

These kind of unique dolphins are threatened by fishing nets
and commercial killing.
Other species in danger is the black or Chilean dolphin, which
lives off the coast of Chile in the Pacific ocean.
There are other dolphin species which are becoming threatened
too, but not as those above.
