When you’re out swimming or surfing at the beach, have you ever wondered which ocean animals surrounding you have teeth? It turns out that sharks aren’t the only marine animals with teeth—a tool in some marine animals may be more widespread than you thought.
From hundreds of sharp, razor-blade-like teeth in great white sharks to the singular long, spiraled tooth on narwhales, teeth come in all shapes in sizes in marine ecosystems. This diversity is for good reason—some use their teeth to shred and slice prey, while others use their teeth more as a harpoon.
Like something out of your nightmares, the fangtooth (Anoplogaster cornuta, Anoplogaster brachycera) lurks in the darkest depths of the ocean. Wielding huge, saberlike teeth, the fangtooth has the largest teeth in the ocean relative to body size. The phrase “relative to body size” is important to remember here, however: the larger of the two species of fangtooth reaches a maximum length of just 6 inches, rendering these tiny balls of ferociousness harmless to humans.
