Earthworms have a remarkable ability to regenerate, which allows them to survive even after being truncated. This regeneration is due to the high differentiation potential of the cells in their bodies, capable of regrowing lost body parts. However, not all parts can be regenerated equally, and in general, only the front end is more likely to regenerate the lost tail, while the rear end is more difficult to regenerate the head and necessary physiological organs. This regenerative ability is a survival strategy in nature, allowing the earthworm to remain alive in the face of predation or external damage. In addition, the regeneration of earthworms also demonstrates their adaptability and importance in the ecosystem, and by promoting soil turning and the decomposition of organic matter, earthworms play a key role in maintaining soil health and promoting plant growth.
