A rare river dolphin has been officially classified as a new species.
The formal announcement was made at a conservation workshop in Santa Cruz de la Sierra in Bolivia.
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.
The boto or Amazon pink river dolphin (Inia geoffrensis) lives exclusively in the freshwater river systems of the Amazon and Orinoco Rivers. The largest of all river dolphins, botos vary from grey to pink and can even change colour, becoming pinker if very active.
Unusually for a dolphin, they have flexible necks and can turn their heads from side to side, weaving between the branches of flooded forests during the wet season.
Both species are hailed as important indicator species for the health of the entire river ecosystem, but are under serious threat from pollution and fisheries.
The adoption of the new species was welcomed by the Whale and Dolphin Conservation Society (WDCS) which warned of the threats facing endangered dolphins.
