Snakes breathe principally by contracting muscles between their ribs. Unlike mammals, they lack a diaphragm, the large smooth muscle responsible for inspiration and expiration between the chest and abdomen. Inspiration is an active process (muscles contract), whereas expiration is passive (muscles relax).
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 dâ¦iffused 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.
