That's it then for the Yangste River Dolphin. It really is tragic that this unique mammal, the last of it's species, has been wiped out by man's activities. There are other river dolphins in S.America but they are a different species. I had hoped that there are some Yangste dolphins in aquariums somewhere that may eventually be re-introduced, but I haven't heard of any. The newsclip I read said that this is the first large mammal to have become extinct in the last 50yrs - does anyone know which mammal was the last one to have this dubious distinction?
