Something you don’t see every day…earthworms mating. Because earthworms have both male and female reproductive organs, when they have sex, they have double the fun.
Once two worms find each other they line themselves up side by side, with the head of one near the tail of the other. They press tightly together, and both worms excrete sperm packets from their male pores. The partner worms receive each other’s packets and store them in their female pores.
Not only do they double the fun this way, they double their offspring making potential.
