Earthworms are hermaphrodite organisms, meaning that each earthworm has both male and female sexual reproduction organs. … Asexual reproduction can also be undertaken by some species of earthworm. This involves a single earthworm producing young from unfertilised eggs and is known as parthenogenesis.
Can a worm reproduce itself?
