Here's a fun fact: Cookie cutter sharks glow in the dark. That's right. They use photophores on their ventral surface to attract prey. Once a larger fish swims up to investigate, the cookie shark uses its lips and upper teeth to suction itself on to the fish. It then spins its body in a tight circle leaving a cookie-shaped hole in the flesh. How great is that? But don't worry, these sharks are so small that they pose little threat to humans.
