BLUE SKINDED SPACE BABES FANTASY RACE LIKELY LIVE SOMPLACE WHERE OXYGEN PRESSURE IS SHIT
WHETHER UNDER THE SEA OR COLD OR IN HIGH ALTITUDES WHERE EVEN THOUGH THE OXY CONCENTRATION IS THE SAME THE DRIVING PRESSURE OF GAS EXCHANGE IN THE LUNGS IS LOW
IN SUCH ENVIRONS COPPER BASED OXYGEN TRANSPORT MECHANISMS ARE ACTUALLY MORE EFFICIENT (ESPECIALLY WHEN ITS BLOBBED UP INTO A PROTEIN THEN THE OXY CONCEBTRATION CAN BE ALMOST IN THE IRON BLOOD RANGE)
THAT COPPER OXIDE BLOOD WOULD GIVE THE HYPOTHETICAL HIGH ALTITUDE SEXY SPACE BABES ALL SORTS OF APPEALING GREEN BLUE AND PURPLE SKIN HUES AND BLUSHES
I CALL IT THE "LIARA FROM MASS EFFECT IS A HORSESHOE CRAB" THEORY
BUT WHAT DO YOU THINK AS A FELLOW SCIENTIST AND BLUEBERRY SQUEEZER?
