Boto Cor-de-Rosa 

The Boto Cor-de-Rosa or Boto (Inia geoffrensis, Platastanidae) is a freshwater river dolphin. The largest of the river dolphins, this species is not to be confused with the Tucuxi (Sotalia fluviatilis), whose range overlaps that of the Amazon River Dolphin but is not a true river dolphin. The neck vertebrae of the Boto Cor-de-Rosa are not fused together, and therefore the Boto is able to bend its neck in a 90 degree angle to its body, and skillfully hunt fish in the flooded forest.In a traditional Amazon River myth, at night a Boto Cor-de-Rosa becomes a handsome young man who seduces girls, impregnates them, then returns to the river in the morning to become a Boto Cor-de-Rosa again.
