Anglerfish
Known for the bioluminescent lure that dangles from its head, which it uses to attract prey in the dark depths of the ocean.
Viperfish
Possesses photophores (light-producing organs) along its body, which it uses to attract prey and communicate with other fish.
Lanternfish
Lanternfish have rows of photophores that help them blend into the faint light above, a phenomenon known as counter-illumination.
Dragonfish
This predator has a unique ability to produce red bioluminescence, which is rare in the deep sea. It uses this to illuminate prey that cannot see red light.
Firefly Squid
Famous for its spectacular light displays, the firefly squid has photophores on its tentacles and body, creating a mesmerizing blue glow.
Cookiecutter shark
Utilizes bioluminescence to disguise its silhouette from below, making it less visible to predators and prey. It has a dark collar that remains unlit, confusing its prey.
Deep-Sea Jellyfish (Atolla wyvillei)
Known for its brilliant blue bioluminescent displays, this jellyfish emits light when threatened, possibly to startle predators or attract larger predators to eat the threat.
Hatchetfish
These fish have photophores on their bellies that produce light to match the faint sunlight from above, making them nearly invisible to predators below.
Crystal Jellyfish
This jellyfish produces a green bioluminescence due to a protein called GFP (Green Fluorescent Protein), which has been extensively used in scientific research.
Flashlight Fish
Named for the bioluminescent organs under their eyes, which they use to communicate, attract prey, and avoid predators.
Barreleye Fish
This fish has a transparent head and tubular eyes that can rotate to see both above and in front. It uses bioluminescence to spot prey and avoid predators.
Siphonophores
These colonial organisms, related to jellyfish, use bioluminescent cells to attract prey and deter predators. Some species can stretch over 40 meters long.
Comb Jellies (Ctenophores)
Although not true jellyfish, comb jellies produce beautiful bioluminescent displays, often resembling a rainbow of colors as their cilia (tiny hair-like structures) refract light.
Hawaiian Bobtail Squid
Engages in a symbiotic relationship with bioluminescent bacteria, which help it camouflage its shadow while hunting at night.
