13. Lizard Fish
While one does not typically expect to see a reptile and fish creature in the same name, you will likely make an exception for the Lizard Fish. It is truly not hard to see why people call it this, as the facial features truly do look like that of a lizard. It is quite possible you have seen one of the numerous different species of Lizard Fish at your local beach.
They tend to live and operate in shallow waters while even those in the deep sea go no further than 400 meters. Despite their lizard-like appearance, they actually are scaleless creatures. They are also transparent, allowing you to see the notable black blotches in their guts. It only serves to make them more horrifying to look at.
