To be clear, I'm not talking about AB, O, A, or B type blood. I'm not talking about different colored blood, either; I saw a bunch of those types of questions earlier. I'm talking about anoxygenic bonding blood, or however you might say it. As biology goes, humans have oxygen-bonding blood, and I'm wondering how it could be applied to alternative biochemistries, such as a methane/ethane one that breathes hydrogen, or a boron/ammonia one,(no clue what it breathes), and stuff like that. http://worldbuilding.stackexchange.com/questions/37554/creating-a-planetary-system-that-can-support-six-different-types-of-biochemistry] This question addresses some of the biochemistries that I would like to do, and where I want to do them. Sorry if this seems rude; I just get so frustrated that nobody else has asked something similar. Here's the ammonia link: http://worldbuilding.stackexchange.com/questions/3090/what-would-an-ammonia-based-world-look-like]
