Go another freedom of the fish. A number of species (salmon, shad, eels, sturgeon, etc..) Bear the same fresh water of the sea, alternate, and regularly move from one to the other. Several families of fish have marine and river species (eg, rays, catfish).

However, this degree of heat, such food, such a habit, seem to set them, corral them in as free element. The warm seas are like a wall for polar species, which are intractable: on the contrary, of warm seas are stopped by the cold currents of the Cape of Good Hope.
