There's a lot of air in the soil; it's not all hard-packed. and they're small, so they don't need a lot. A lot of worms move the dirt through their digestive systems, extracting nutrients, and then spitting it out the back, and they have stiff hairs at the back to help them grip as they expand and contract their segments as needed.

Worms have no lungs to breath. Their moist skin allows them to "breath" oxygen into their body and release carbon dioxide from inside their body into the surrounding bedding.
cool man...

well they eat the soil as they move along, and they shove through the soil with their stretch/compress movements, and breathing, they prolly dont require much oxygen.

They breath thru their skin.
