Blackspotted Puffer
Arothron nigropunctatus
A large Indo-Pacific reef puffer with a bluish to gray body covered in black spots and a beak-like mouth. It is common around coral and rocky reefs, where it grazes on hard-shelled invertebrates and algae.
Identification points
- Blue-gray body covered with distinct black spots, especially on the sides
- Rounded puffer shape with a blunt head and small dorsal and anal fins set far back
- Beak-like fused teeth visible at the front of the mouth
Habitat
Shallow coral reefs, reef slopes, lagoons, and outer reef flats in tropical Indo-Pacific waters; typically seen close to structure where it can shelter in crevices.
Bait notes
Not a standard target species and is generally poor table fare. It may take small pieces of shellfish, squid, or crab offered near reef structure, but angling for it is usually incidental rather than intentional.
Behavior
Feeds by biting off pieces of coral-associated invertebrates, algae, and small benthic prey with fused teeth. Often wary but can be approached on reefs; inflates when threatened.
Caution
All pufferfishes can contain tetrodotoxin; do not eat unless local regulations and expert identification support it, and even then consumption is generally not recommended. Its skin and mouth are also best handled cautiously.
Fishing notes
If encountered, use light reef tackle and small hooks or bait rigs near coral and rocky edges. Handle carefully, avoid forcing it from structure, and minimize air exposure; many puffers are better released.
