Definition

Noun: 1. A type of fish characterized by a bioluminescent organ located beneath each eye: This definition refers to a specific marine fish known for its ability to produce light.

A fish adapted to deep, dark ocean environments with light-producing capabilities: This meaning emphasizes the fish's habitat and its primary biological adaptation—the presence of photophores (light organs) below its eyes, which it uses to navigate and hunt in low-light conditions.
