DRAGONFISH
Sure this fish is only about 6 inches in length but considering the size of their teeth and their ferocious behaviour, I wouldn’t want to come across one while swimming.
Did you know?
Many prey species that the Dragonfish feed on produce their own light source. As a result, this deadly predator has a black stomach. After all, you don’t want your latest meal to show the rest of the underwater world where you are, right?
