Reproduction
Cannot fertilize own eggs
Mating occurs when worm join head to tail
Forms mucus coat around intertwined bodies
Each injects sperm into the mucus
Sperm move to seminal receptacle
Eggs in body cavity move through genital pore
Clitellum- Swelling around the sex organs- produces mucus sheath
Worm wiggles to slip the sheath off its body; eggs and sperm are joined
