Heartworm (Dirofilaria immitis)
The heartworm is a disease filled worm that causes filariasis. It does not possess a complex set of respiratory organs to breathe. The heartworm breathes through diffusion, where the amount of oxygen in the worm is less than the amount of oxygen outside of the worm. It needs to stay moist so the oxygen can easily slip into the worm and carbon dioxide can just as easily come out.
Red Stomach Worm (Haemonchus contortus)
The red stomach worm is a parasitic worm that is found in the stomachs of many animals. Like the heartworm, the red stomach worm breathes through diffusion. The skin of the worm is protected by a cuticle, and the worm stays moist from the mucus. If the worm is dry, then gases will not be able to exchange, leaving the worm unable to breathe. The red stomach worm needs to stay wet in order for gases to be inhaled and exhaled properly.
Roundworm (Nematoda)
The Roundworm is an infectious worm that lives in the intestines of many animals, including people. It is exactly like the other worms, where it breathes through diffusion. Although they need to stay moist, they can not be to wet. If the worm is thoroughly drenched, then it might drown. The roundworm needs a balance of both water and air at times. However, if the surrounding waters also have room for air, the worm can stay their for a long time. Due to the fact that the worms are very thin and small, the oxygen goes directly into the bloodstream from the skin.
