One morning I noticed two worms stuck together on the ground. Before I got a good eyeful, my dog rudely interrupted them and they hastily retreated into their burrows. Were they soil mates discussing Nietzsche or niches over a cup of dirt? Being hermaphroditic enhances the chances of finding a suitable mate for creatures like worms, with limited access to partners or the internet. And they may prefer a partner because mixing genes is a good way to hedge genetic bets in ever-changing environments. Even so, self-fertilization parthenogenesis may be more common than generally reported.

Earthworm Reproduction | HowStuffWorks

Although small, earthworms provide big benefits to soil by aerating it as they burrow and enriching it as they eat and excrete organic material. One myth of earthworm reproduction is that if you cut them in half, the two halves will regenerate into two new worms. Although worms can regenerate small portions of their bodies, they do not reproduce this way. From hermaphrodites to mucous cocoons, earthworm reproductive habits are more fascinating than the myths. Earthworms are members of the annelid phylum. The word "annelid" means "small rings"; if you look closely at an earthworm, you'll see that the body appears to be surrounded by small rings.

How Earthworms Work

Science Insights, Addison-Wesley, 3. They are the main contributors to enriching and improving soil for plants, animals and even humans. Earthworms create tunnels in the soil by burrowing, which aerates the soil to allow air, water and nutrients to reach deep within the soil. Earthworms eat the soil which has organic matter such as decaying vegetation or leaves. Plants cannot use this organic matter directly.
One of the most interesting aspects of earthworms is their sexuality. Earthworms are simultaneous hermaphrodites , meaning worms have both male and female reproductive organs. During sexual intercourse among earthworms, both sets of sex organs are used by both worms. If all goes well, the eggs of both of the mates become fertilized.
