Flatworm

Damp soil, leaf litter, rotting logs, and aquatic environments ranging from freshwater to marine ecosystems.

Predatory or scavenger; feeds on small invertebrates like earthworms, snails, and slugs by secreting digestive enzymes.

Nocturnal and moisture-dependent; they move using cilia on a layer of mucus and can regenerate from body fragments.

Invasive species can deplete local earthworm populations; they are generally harmless to humans but some species produce toxins like tetrodotoxin.
