Long-spine Porcupinefish
Diodon holocanthusAlso known as Balloonfish, Freckled Porcupinefish, Porcupine Puffer, Porcupine Pufferfish
Long-spine porcupinefish navigate shallow reefs with a slow, hovering flight powered by their pectoral fins, searching for hard-shelled prey to crush with their powerful beak-like teeth. When threatened, they swallow water to inflate their bodies into a formidable, spine-covered ball that deters most predators. During the day, they often seek shelter under ledges, emerging at night to hunt actively along the seafloor.

Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Internal organs contain lethal tetrodotoxin, and the strong beak can deliver a painful bite if handled.
- Why it is dangerous
- Contains tetrodotoxin in its skin and internal organs, which is extremely lethal if consumed. The powerful beak-like teeth can easily crush fingers.
- How to recognize a risky encounter
- Look for long, foldable spines, a pale body covered in small black spots, and large, expressive eyes.
- What to do
- Never attempt to touch, catch, or handle this fish; admire its unique swimming style from a safe distance.
Responsible observation
- Keep your distance: Avoid provoking or cornering them, as inflating causes them significant physical stress.
- Watch for eye movement: Observe their expressive, independently moving eyes as they scan the reef.
- Look under ledges: Search shaded crevices and caves during the day where they rest.
