do worms have lungs
Their skin must remain moist for them to breathe. Like us, they still need to take in oxygen and expel carbon dioxide. However because they don't have lungs, this process happens though their skin. It's not uncommon to see worms coming to the soil surface after saturating rains. Some hold the view that they suffocate in water saturated soil because there isn't enough oxygen. However worms can survive for some time in water.
