So I randomly just decided to start researching snake anatomy (partly out of curiosity of how in the hell they breath when you give em a big meal lol). First thing I noticed was a half debunking of the "snakes only have one lung line". This is seemingly sorta true as their left lung is vestigial in most species compared to the right lung. Although the right lung has alot of extraneous room not used for gas exchange. I'm also seeing some reference to the fact that with some species more that are more water centric that vestigial lung isn't quite so vestigial. Got me to wondering if this is the case with garters. Does anyone know specifically about garter anatomy enough to know if they have this extra lung capacity? Something tells me they would need it between their affinity for hunting fish and their general really active nature. Not trying to enter Delilah in a diving contest or anything, I'm just a really sciency person and I have to know the ins and outs of everything in my world I interact with often enough
