The anglerfish is so called because of its method of predation. This is the fish that goes fishing. It has a long, modified dorsal fin spine sprouting from the middle of its head that ends in a fleshy growth that can move and wiggle to resemble another animal. In some deep sea anglerfish this deadly bait can even emit light (bioluminescence). Passing predators who think they’ve found an easy meal only need to touch the bait to find out they’re the main course.
