This is the anglerfish. It is scary right? But look at the rod on its head! It is called a lure. Bacteria living in the lure makes the lure glow. This helps it to attract prey or even a mate. The anglerfish male is about 20 times smaller than the female! What is weird? To mate, the male anglerfish uses special teeth and cling on to the belly of the female. Then, it stays there for the rest of its life. On the fourth picture, can you see the male circled in red? The hairy angler species (below) has hair like things. It detects the movement of prey.
