The Humpback anglerfish (Melanocetus johnsonii) is a tiny deep‑sea predator famous for its bioluminescent lure that dangles from a modified dorsal spine. At only about 2.9 cm long, it inhabits the dark waters of the open ocean and is rarely encountered by humans, making it a curiosity rather than a sport fish.
