Lanterneye fishes

Anomalopidae

Anomalopidae are a unique family of fish that possess notable characteristics in the form of bioluminescent organs positioned below their eyes, from which their name derives. These specialized light organs accommodate luminous bacteria and can be controlled by the fish, either by employing a dark lid or by retracting them into a pouch. They serve crucial functions such as communication, prey attraction, and predator avoidance.
