Anglerfish on seafloor


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. Having been lured inside the anglerfish's wide mouth, the long pointed teeth snap shut and the creature is devoured whole. There are more than 300 species of anglerfish worldwide. They are found in open water and on the sea bed. Some of the bottom dwellers have modified fins that let them walk along the ocean floor.
