Quick answer
Earthworms (Lumbricina) typically live around 1–6 years (varies by species). Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Key takeaway

Earthworm lifespan in the wild
Field and museum records place most earthworms near 1–6 years (varies by species). That figure blends ages at death across regions, so treat it as a planning range. Body size (about 0.005 kg) and risk lifestyle both shape the average.
What shortens earthworm lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever earthworms share landscapes with people.
What helps earthworms live longer
Connected habitat, low chronic stress, and reliable food support longevity. For captive or domestic relatives, species-correct diet and veterinary screening matter more than generic “pet” advice.
Earthworm life stages
Juveniles usually face higher mortality than prime adults. Older animals may move less, show dental wear, or lose body condition — useful signs when ageing earthworms in the field.
Diet and digestion
Earthworms are detritivores that feed on decaying leaves, roots, and other organic matter in the soil. Because they have no teeth, they swallow small stones and grit that grind food inside a muscular gizzard. Their digestion releases nutrients in a form plants can readily absorb.
Reproduction and regeneration
Earthworms are hermaphrodites, with each worm carrying both male and female organs, but two worms still mate to exchange sperm. After mating, a band on the body called the clitellum forms a cocoon in which the eggs develop. Some species can regrow a lost tail end, though they cannot regenerate a whole new worm from any piece.
