Caribbean Giant Centipede
Scolopendra alternansAlso known as Haitian Giant Centipede, Florida Keys Centipede
Caribbean giant centipedes are nocturnal invertebrate predators that stalk forest floors and limestone crevices across the West Indies and South Florida. Equipped with powerful modified front legs known as toxicognaths, they overpower insects, small reptiles, and amphibians before dragging them into dark retreats. Their elongated, segmented bodies allow them to navigate tight burrows with remarkable agility while seeking refuge from daylight.

- Moderate
- High
- Very high
- Why interaction risk is very high
- Delivers a painful venomous bite with modified pincer legs; observe safely without touching.
- Why it is dangerous
- Injects venom through strong pincer-like legs that causes severe throbbing pain, local swelling, and skin inflammation.
- How to recognize a risky encounter
- Recognized by its long flattened body with dark brown to reddish segments and bright yellowish-orange legs.
- What to do
- Never handle with bare hands; allow the animal to move off freely if uncovered during field exploration.
- What to notice
- Look for large, dark, multi-segmented centipedes under limestone slabs and decaying wood in hardwood hammocks.
- Support conservation
- Keep microhabitats intact by returning flipped logs and rocks to their exact original positions.
Responsible observation
- Night Viewing: Search moist leaf litter or rotting logs after dusk using a red light to minimize stress.
- Safe Distance: Refrain from turning over surface debris with bare hands where centipedes take shelter.
