Anglerfish

This dangerous fish besides being in these top 10 most dangerous fish should also be in the top 10 world’s ugliest animals. It lives in deep waters, especially in the depths of the Atlantic and Antarctic oceans. The main characteristic of this fish is his mode of predation, because it has a fleshy growth from his head that acts as a lure; and at the tip of this lure there is a luminous trap that it uses to attract preys and then devour them. Lastly, despite being small he has the ability to expand his jaw and stomach to eat even bigger animals than it.
