Description

The Atlantic flashlightfish is a remarkable nocturnal fish from the western Atlantic, in the Caribbean. The species grows to about 12 cm and has a stocky, dark body and beneath each eye a large light organ that gives a bright blue-green light through symbiotic luminous bacteria. With a skin flap it can switch this light on and off to lure prey, communicate and mislead predators. It lives on deep reef slopes and comes to shallower water at night. The fish is harmless to humans and has not been evaluated by the IUCN (NE).
