### Instruction: What are red wigglers?
### Response: Their true name is eisenia fetida and is known as the most common compost worm. These worms are not found in the soil but rather live in the upper layers of organic matter.

The worms have gizzards like chickens. They are hermaphroditic which means they have move male and female sex organs. It takes two worms to produce a cocoon which could produce three worms each.

The worms produce vermicast (worm poop) which many organic famers use to add to their soil.
