Reserve Pantanal Swamp. It seems that it may be... darker? It turns out and swamp can be beautiful enough to be reserved place on the planet. The marshes of the Pantanal, the spread on the territory of Brazil and exciting small fate of Bolivia and Paraguay - here is concentrated the largest number of animal species on Earth! Some of them appeared here, as the giant anteater or capybara (water hogs came up), others simply suppress its numbers. You can imagine millions of crocodiles? If not, come to the Pantanal! Just live here in about 3500 species of plants, 650 species of birds, 80 species of mammals, 50 kinds of reptiles, 230 species of fish.
