Then there are other times when turtles breathe out the other end, more specifically, through what scientists call the cloaca.

Reptiles, amphibians, most birds, and monotremes like the platypus have a cloaca, a multipurpose swiss army knife of holes, linking the urinary, waste, and reproductive systems… I guess you could say: one ring to rule them all.
