White-spotted Puffer
Arothron hispidusAlso known as Stars and Stripes Puffer, Bristly Puffer, White-spotted Blowfish
White-spotted puffers cruise solitary over tropical coral reefs and sandy lagoons, using their fan-like fins for precise, hovering maneuvers. When threatened, they rapidly gulp water into an elastic stomach to swell into an intimidating, spiny sphere that deters predators. Their powerful beak-like dental plates easily crunch through hard-shelled invertebrates like crabs, sea urchins, and branching corals.

Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Tissues contain lethal tetrodotoxin if ingested, and fused teeth can deliver a severe bite if handled.
- Why it is dangerous
- Internal organs and skin contain tetrodotoxin, a potent neurotoxin that blocks sodium channels, causing paralysis and fatal respiratory failure when ingested.
- How to recognize a risky encounter
- Look for a grey or yellow body dotted with white specks and encircled by concentric white rings around the eyes and pectoral fins.
- What to do
- Never consume this fish and avoid cornering or touching it during dives to prevent a painful, crushing bite.
Responsible observation
- Diving Etiquette: Maintain respectful distance and never chase or provoke a puffer into inflating, as the stress depletes its vital energy.
- Handling: Do not attempt to touch or catch puffers by hand, as their beak-like jaws can sever fingers and inflict painful wounds.
