Land Planarian (Hammerhead Worm)

Damp, humid environments such as under leaf litter, logs, or soil in gardens and greenhouses.

Carnivorous; they primarily eat earthworms, slugs, and snails by liquefying them with enzymes.

Nocturnal and moisture-dependent; they move via a sliding motion on a mucus trail and can reproduce through fragmentation.

Potential risks: They are invasive in many regions and can contain tetrodotoxin (a potent neurotoxin); they disrupt soil ecosystems by preying on beneficial earthworms.
