7/31.- National Park of Manuel Antonio, howler monkey

In the picture you can see a howler monkey. These monkeys' howls are scary, making the whole jungle tremble. The first time I heard them, I did not see the monkeys themselves; I only saw the branches from the tallest trees around me shaking. Their howling voices resembled that of King Kong, or the dinosaurs in Jurassic Park; but when I saw them, I was surprised to see how small they were.
