Where do black arowanas live?
assistant
Black arowanas were discovered in the 1970s in the Orinoco basins, but whether this is a natural population or the result of introductions by humans is disputed. It is essentially a sedentary (non-migratory) species of blackwater habitats. During the dry season it mostly inhabits backwaters, marginal lagoons and small tributaries, but it is often seen in flooded forests during the high water season.
