I get the joke, but the Tigerfish is African. It is the only fish thought to be able to navigate up and down the tremendously deep and swift Congo river. In places it is so deep there are blind, deep-sea like fish. In others, there is so much water shear that species evolve differently on different sides because the current is too strong to get to the other side. The Tigerfish appears to be able to move at will, as the biggest, strongest, apex predator in the river.
