Discovered in the pitch-black abyssal zone, the fireworks jellyfish (Halitrephes maasi) earns its name from its spectacular bioluminescent display—vibrant orange and pink tentacles that explode like celestial pyrotechnics in the ocean’s darkest depths. Thriving between 1,200 and 1,500 meters, this gelatinous creature has captivated marine biologists with its otherworldly appearance and mysterious life cycle.
