Earthworms are hermaphrodites with both male and female reproductive organs. On warm, moist spring and summer nights, you can often seen hundreds of mating worms coming up out of their burrows. Once they have mated, the girdle like ring around the front of an earthworm, called the clitellum slides along the worm's body, picking up fertilised eggs. When it finally falls off the worm into the soil, it forms a well protected nest or egg case within which the embryo worms develop. |
