Natural Habitat

Moist soil, rich in organic matter. They are typically found in gardens, forests, grasslands, and agricultural fields.

Diet & Feeding

Decomposing organic matter, including dead leaves, plant debris, and microorganisms in the soil. They ingest soil as they burrow, extracting nutrients.

Behavior Patterns

Nocturnal activity, burrowing through soil, hermaphroditic reproduction (each individual has both male and female organs but requires a partner to reproduce). They pull organic matter into their burrows. Rapid regeneration of lost segments.

Risks & Benefits

Benefits: Essential for soil health, aeration, drainage, and nutrient cycling. Their burrows improve water infiltration and root growth. Their castings enrich the soil with nutrients. Risks: Generally no direct risks to humans. Can sometimes be vectors for certain plant diseases, but this is a rare and minor risk compared to their significant benefits.
