Narrowlined Puffer
Arothron manilensis
The Narrowlined Puffer (Arothron manilensis) is a tropical Indo-Pacific reef and lagoon puffer with a blunt body and fine dark lines. It is not a major angling target and, like other puffers, should be handled carefully because of toxic tissues.

Identification points
- Blunt, rounded puffer body with no obvious spines
- Fine dark longitudinal lines or narrow striping on a pale body
- Small mouth and large eyes set high on the head
Habitat
Shallow coral reefs, reef flats, lagoons, seagrass beds, and protected coastal areas in tropical waters; often near rubble, sand, and reef edges.
Bait notes
Not a common sport species; if encountered, small pieces of shrimp, squid, crab, or mollusk may tempt it. Small bottom jigs or tiny baited hooks used for reef bycatch can hook it.
Behavior
Benthic and slow-moving, feeding on small hard-shelled invertebrates and other reef items it picks off the bottom. It may inflate when stressed and is generally a wary, non-schooling reef fish.
Caution
Potentially poisonous like other puffers; do not eat unless local experts specifically confirm edibility. Skin, organs, and sometimes flesh can contain tetrodotoxin, and handling is best minimized.
Fishing notes
Best treated as incidental bycatch around reefs and lagoons rather than a target. Use light tackle and small hooks if you need to observe or release it; avoid prolonged air exposure and handle minimally.
