Family : Lanterneye fishes ; Occurs along seaward reefs near or along steep drop-offs with caves. In some areas it may approach the surface. Usually feeds in large groups away from the reefs at night. Well hidden in caves during the day and rarely seen. Usually observed at night.

Species Photoblepharon palpebratum
Eyelightfish have a blunt
snout, a large upturned mouth
, a deeply
forked caudal fin
, and a light-emitting organ, called a photophore,
under each eye. The lateral line arches over the pectoral fins, and
each scale has a prominent
white or blue spot.
These fish are dark purplish-gray in color, with heads darker than their bodies. A bluish-white area behind the head extends onto the base of the pectoral fins, which are black. The other fins are usually a dark purplish-brown.
Size and Weight : This species can reach a length of 12 cm (4.7 in). Females are larger than males.
The bioluminescent photophores contain billions of symbiotic light-emitting bacteria, that produce a bright, lime-green light by generating chemicals similar to those used in commercially produced light-sticks. This is an example of a mutalistic relationship—the fish benefit from the bacteria providing them with light and the bacteria benefit by getting nutrients and oxygen from the fishes’ blood, as well as a safe home .
Biome: Saltwater . Reef-associated .
They are nocturnal , staying well-hidden during the day and emerging at night to feed on zooplankton , which are attracted to the light from the photophores. They also eat the smaller fishes that come to share the zooplankton. Normally, these flashlightfish feed in currents just out from the reef wall. On dark, moonless nights, they also feed near the surface of the water.
Eyelightfish have a large, bean-shaped, light organ
(called a photophore)
below each eye. While the light is produced
constantly, the fish
the light “on and off” by raising and lowering a membrane
to an eyelid
), that veils
the photophore. While the fish usually
blink 2-3 times per minute, when facing danger, they can flash their
light up to 50-70 times per minute.
The blinking of these light organs is used to communicate with fellow eyelightfish, to assist in schooling and mating, and to attract prey . Predators are confused by the use of a “blink and run” strategy, in which the fish rapidly swim in one direction with their lights “on”, then switch directions and swim with the lights “off”.- somewhat like turning a flashlight on and off.
