Hammerhead Worm

Moist terrestrial environments such as gardens, greenhouses, and leaf litter; native to Southeast Asia, now invasive worldwide.

Carnivorous predator of earthworms, slugs, insect larvae, and other soil invertebrates.

Nocturnal and moisture-dependent; hunts by following slime trails and uses neurotoxins to immobilize prey. Reproduces both sexually and via fragmentation.

Invasive species that harms ecosystems by depleting earthworm populations. They produce tetrodotoxin (a neurotoxin) and should not be handled with bare hands; may cause skin irritation.
