The Anglerfish

The anglerfish grows its own special bioluminescent bacteria to attract prey. The scary-looking fish uses a luminescent lure packed with glowing bacteria that hangs just above and in front of its toothy face. But it's only the females that have this "fishing pole," which is actually a piece of dorsal spine containing millions of glow-in-the-dark bacteria. Yes, the anglerfish is the very same deep-sea fish that terrorized Nemo and Dory in Pixar's "Finding Nemo." There are more than 200 species of anglerfish, many of which live at the bottom of the Atlantic and Antarctic oceans. Above is one of the species, the ferocious-looking monkfish.
