How does an echidna breathe?

Echidnas breathe through their lungs, similar to other mammals. They have a unique respiratory system that allows them to efficiently take in oxygen, which they do through their snouts. When foraging, echidnas can also use their long tongues to capture insects while simultaneously breathing, as their snouts are designed to facilitate both feeding and respiration. Unlike some other mammals, echidnas do not have a diaphragm; instead, they rely on the expansion and contraction of their body cavity muscles to aid in breathing.
