Sure, cookie cutter sharks are only 50 cm (19 inch), but you don’t wanna mess with these guys. Cookie cutter sharks get their name from the holes they leave when biting into the the flesh of various marine mammals and fish (there have been reported attacks on humans as well). They do this by latching on with their sharp, saw-like teeth and spinning around 360 degrees until they get a nice chunk of flesh. Yum.

Considering they live in the deeper seas, about 3.7 km (2.3 mi) beneath the surface, they are bioluminescent. Their whole underside glows to mimic the sunlight from the surface, this camouflages their silhouette from certain predators that lurk below them. At night, they migrate up closer to the surface to hunt for their food with those scary, scary, set of teeth.

    Where’s the upper row of teeth? Or do they permanently bite themselves? Perhaps biting themselves is even more fun than...
