Humpback Snapper

Lutjanus gibbus

Humpback Snapper (Lutjanus gibbus) is a reef-associated snapper of the tropical Indo-Pacific, often found in schools over coral and rocky bottoms. It is a nocturnal predator that feeds on small fishes and crustaceans and is occasionally taken by reef anglers.

Identification points

Deep-bodied snapper with a steep, strongly sloped forehead and noticeable nuchal hump
Body typically reddish to pinkish with rows of pale blue lines/marks on the head and upper sides
Caudal fin is slightly emarginate to truncate, with a darker edge in many individuals

Habitat

Tropical Indo-Pacific coral reefs, reef slopes, lagoon passes, outer reef drop-offs, and adjacent sandy or rubble bottoms; usually from shallow inshore reefs to deeper offshore reef structure.

Bait notes

Small live baits like pilchards, herrings, sardines, shrimp, and squid strips work well; cut bait from reef fish also takes fish. Small jigged metal or soft plastics can work when fish are actively feeding.

Behavior

Mostly nocturnal and crepuscular, sheltering by day around reef relief and foraging at dusk and night. It schools as juveniles and smaller adults and feeds on small fish, shrimp, crabs, and other benthic prey.

Caution

Reef fish from tropical waters can carry ciguatera risk depending on location and size; avoid eating very large individuals from known risk areas. Handle reef structures carefully to avoid cuts from coral and spines.

Fishing notes

Fish reef edges, drop-offs, and current lines with light to medium tackle and enough leader abrasion resistance for coral. Best results often come at dawn, dusk, or after dark using bottom rigs, slow retrieves, or free-lined live bait.
