Astronesthes splendidus
The Splendid snaggletooth (Astronesthes splendidus) is a small, bioluminescent deep‑sea fish reaching about 12 cm in length. It inhabits the mesopelagic zone of tropical and subtropical oceans and is attracted to light, making it a niche target for night‑time deep‑water anglers. Though not sought after for food, it can be caught for scientific study or as a unique novelty catch.
