Fin's Fish Guide
The Eyelight fish (Photoblepharon palpebratum) is a saltwater fish of the family Anomalopidae that grows up to 12 cm.
Description
The eyelight fish is a small reef fish of the flashlight fish family (Anomalopidae) from the Indo-West Pacific. The species reaches about 12 cm and is largely black. Beneath each eye it carries a large light organ filled with symbiotic luminous bacteria; with a fold of skin the fish can 'blink' this light on and off. It lives along steep reef slopes with caves, where it stays hidden by day. At night it often forages in large groups some distance from the reef on zooplankton. The blinking light serves to attract prey, communicate and confuse predators.
