Key identification features
- Round, heavy-bodied puffer reaching about 30-50 cm (12-20 in)
- Most common form: dark brown to blackish body densely covered in small, uniform white spots
- Less common yellow morph: solid bright yellow body, sometimes with faint spotting
- Large, prominent eyes and a blunt, rounded snout
- Thick lips and a beak-like fused tooth plate typical of pufferfish
- No pelvic fins; slow swimming style using pectoral, dorsal, and anal fins
Common look-alikes
- Blackspotted puffer (Arothron nigropunctatus): has fewer, much larger, widely spaced black spots on a pale gray or yellow background, opposite of the Guineafowl's dense small white dots on dark skin.
- Star puffer species: generally show larger, more irregular blotching rather than fine, evenly sized spots.
Where you'll see one
Common on coral reefs and rocky reef areas throughout the Indo-Pacific and Eastern Pacific. It is typically seen resting near ledges, caves, or coral heads during the day and foraging over reef substrate for sponges, tunicates, and other slow-moving invertebrates.
Frequently asked questions
How do I recognize the two color forms of the Guineafowl Pufferfish?
Look for either a dark brown to black body covered in fine white spots, or the less common solid bright yellow form; both share the same rounded body shape.
How do I tell it apart from a Blackspotted Puffer?
The Guineafowl has many small, densely packed white spots, while the Blackspotted Puffer has fewer, much larger dark spots scattered over a paler body.
