Anomalopidae (lanterneye fishes or flashlight fishes) are a family of fish distinguished by bioluminescent organs located underneath their eyes, for which they are named.
These light organs contain luminous bacteria and can be “shut off” by the fish using either a dark lid or by being drawn into a pouch. They are used to communicate, attract prey, and evade predators.
These rarely seen fish are nocturnal and found in the Indo-Pacific Ocean and Caribbean Sea.
