Rare Bolivian river dolphin is new species

This story is a couple of months old already, but I thought it was an interesting development. It seems that the Bolivian river dolphin has now been acknowledged as a separate species to the more commonly-known Amazon River dolphin. The Telegraph has the story.

The formal announcement was made at a conservation workshop in Santa Cruz de la Sierra in Bolivia.

The Bolivian dolphin (Inia boliviensis) was immediately adopted by the Bolivian government as a symbol of the country's conservation efforts.

The Bolivian species is smaller and a lighter grey in colour than the other species and has more teeth. It lives only in the Bolivian Amazon and is isolated from the other Amazon River dolphins, separated by a series of 18 rapids between Bolivia and Brazil.
