Undulated Moray
Gymnothorax undulatus
The Undulated Moray is a large reef-dwelling eel with a strongly wavy pattern and a broad Indo-Pacific presence in shallow coral and rocky habitats. It is mostly nocturnal, secretive, and not a targeted game fish, though it will strike fishy baits when approached near its lair.

Identification points
- Long eel-like body with a pale tan to yellow base color covered in dark, irregular wavy bars or undulations
- Broad head with a blunt snout and small eyes typical of morays
- Dorsal, anal, and caudal fins joined into one continuous fin fringe along the body
Habitat
Coral reefs, surge channels, outer reef slopes, and rocky crevices in shallow tropical marine waters; often hides in holes and ledges by day.
Bait notes
Fresh fish chunks, squid strips, and oily baits work best; large live or cut bait near reef structure can draw strikes, but it is usually an incidental catch rather than a planned target.
Behavior
Nocturnal ambush predator that waits inside crevices and feeds on fish and crustaceans at night; can be territorial and may bite if cornered or hooked near its refuge.
Caution
Strong jaws and sharp teeth can inflict serious bites; handle with extreme care, and avoid reaching into holes. Like many large reef predators, it may carry ciguatera risk in some areas and is often not considered a safe food fish.
Fishing notes
Fish after dark around reef edges, drop-offs, and holes with stout gear and abrasion-resistant leader; keep the bait tight to structure and use quick, controlled pressure to keep it out of the rocks.
