16. Dragonfish
The dragonfish, Grammatostomias flagellibarba, is a deep sea monster that lurks around the Atlantic seaboard of North America and Africa. These monsters are known for the glowing barbel that they eventually develop, allowing them to create light with their own body chemicals. Although they are terrifyingly ugly, with their razor sharp teeth protruding out of their mouths, they only reach about seven inches long.
