The Fangtooth Fish ( Anoplogaster cornuta) is a creature that is found in the depths of many of the world’s oceans. The Fangtooth gets its name from its huge teeth, the largest teeth of any fish in the ocean when compared to its body size. Belying its ferocious appearance, the Fangtooth it is actually a small fish, reaching a maximum length of only six inches, with a disproportionately large head and mouth and a short, deep body.
