Living about a mile below the ocean surface, the Viperfish looks truly frightening. They are generally entirely black except for certain parts of their body that illuminate to attract their prey. Beyond these evolutionary enhancements, Viperfish also have large eyes to help them see their prey in the utter darkness they inhabit and spear-like teeth that give them their uniquely terrifying look.
Say hello to another deep-sea monster: the anoplogaster cornuta, or Fangtooth. Due to its enlarged head and fearsome appearance, it has also been dubbed the “ogrefish.” This fish lives at a depth of 16,000 feet where it must be able to survive both the extreme pressure and water temperatures near freezing. These extreme living conditions have caused the fangtooth to adopt anliberal diet: these fish eat almost anything they can find. Rest assured, though, even if you ever did come face-to face with one of these fish (not likely because of the depth at which they live), they would be much less scary than the picture: the largest Fangteeth only grow to be 6 inches in length.
