They line up their clitellums -- thickened sections of their bodies that contain their reproductive organs -- and exchange sperm packets.
Sheaths form around their clitellums, which dry and fill with albumin.Once earthworms have mated, they go to some effort to fertilize them. It takes between 10 and 55 weeks for them to mature to their full adult size.Once earthworms have reached adulthood -- that age varies according to species -- they're sexually mature and ready to produce the next generation.
