description Splitfin Flashlightfish Overview

The splitfin flashlightfish is a nocturnal marine fish belonging to the family Anomalopidae, found in the tropical Indo-Pacific region. It is distinguished by specialized bean-shaped organs located beneath its eyes that house symbiotic bioluminescent bacteria. The fish can rotate these organs to control the emission of light, using the blue-green glow to locate prey, communicate, and avoid predators. During the day, this species typically seeks shelter in the dark environments of underwater caves and deep reef slopes.
