Earthworms respire and take in oxygen directly from the skin and releases co2 from the skin as well.
It has no vascular system so it gets all it's oxygen through diffusion through it's skin if that's what you mean. In other terms its individual cells respire just as any other animal cells would.

Earthworms breathe through their moist skin. Gas exchange takes place directly there.
The Earthworm's body has to stay moist & slimy because it allows oxygen to be diffused from air through the skin. This allows the worm breath because they do not have lungs.
They do not breathe as we do- they take in oxygen directly through their skin, and give off carbon dioxide the same way.
They use their skin [integument] to support the process of gaseous exchange known as transpiration.
Through their pores.
Diffusion allows an earthworm to get the oxygen it needs to survive. Remember, an earthworm needs oxygen just like we do, and its cells are constantly using oxygen to perform cell processes. This means the amount of oxygen inside the earthworm will always be less (lower concentration) than the area outside of the earthworm (higher concentration). This is great news for the earthworm! New oxygen from the environment is constantly diffusing into the cell to replace the oxygen that is used up.
hope this helps, :)

The earthworm, is, in fact, a mammal. Earthworms, or the genus mammilus wormisammaliasis, breathe out of a lung-related apparatus, unique to the wormisammaliasis. This apparatus, known coincidentally as their cigarette, is the only means for the earthworm to help for breathe. You're welcome.
Earthworms do not have lungs. They directly absorb oxygen into their bodies through their skin.
earthworms travel faster
The bacteria in earthworms is called Eisenia Fetida it's in most earthworms
earthworms penises are longer
Potting mix does not kill earthworms.
Earthworms are examples of annelid worms (Phylum Annelida), which also contains leeches and many typres of marine worms. Earthworms are from the Class Oligochaeta, which contanins the earthworms, some freshwater worms and leeches.
