The anglerfish is a deep-sea fish known for its unique method of attracting prey. It has a bioluminescent lure on its head, which it uses to entice smaller fish. When a curious fish approaches, the anglerfish quickly snaps it up with its large mouth and sharp teeth. There are over 200 species of anglerfish, found in various ocean depths. They typically have a flattened body and can vary in size, with some species growing up to three feet long. Anglerfish are also known for their unusual reproductive habits, where some males become parasitic on females.
