Can mammals breathe through their rectums to save lives?

Science · Published 8 October 2026 Swipe more like this →

In short: While it sounds like science fiction, researchers have discovered that certain mammals possess the ability to absorb oxygen through their digestive tracts, a biological mechanism that could potentially be harnessed for medical purposes.

Scientists have long observed certain animal species utilizing their rectums for respiration. Recent research has expanded this understanding to include specific mammals, confirming that they can indeed breathe through their butts. This physiological capability opens new avenues for medical research into how oxygen might be delivered to the body via the digestive system.
