The discussion could be relevant to more than just the original poster if other people with similar cases find the same thread later. If the OP is forced to state their jurisdiction, the discussion might be more focused, but potentially less useful to others.

I’d just call that respiration. Every definition of breathing I can find is particular to lungs.

Edit: Actually, that’s not true—I found a dictionary that lists a broader metaphorical usage that encompasses all respiration (including plants and fish).

The article you linked doesn’t discuss how the DR evolved, but it seems more likely to result from the occasional risk of submersion faced by most land animals, rather than something they all inherited from fish (who neither breathe nor sleep).

That’s an easy hypothesis to test, because all land vertebrates have fish ancestors.

Do you see all land animals washing their faces with cold water to wake up?

I loved the way the different storylines and characters were tied together, some intricately and some just loosely, as well as the multiple perspectives, timelines, and storylines.
