    Chlorocruorin is really confusingly named. I was trying and failing to find the chlorine in it and was wondering if I was just dumb or blind or what.

    khloros is Greek for “green”. That’s also where chlorine gets its name. So they’re only related etymologically.

    Interesting tidbit: from left to right, these are ordered by the efficiency of the oxygen transportation, highest to lowest.

    Blue blood may be cool, but red blood is better for you.

      I guess I could google it but for the sake of the comment section is that from highest to lowest or the other way around?

    I remember one of my sister’s teachers were saying that human blood is blue when inside your body. “Just look at your veins!”

    Amazing that Vulcans aren’t mentioned on this list. And on a more serious note: humanoids with green blood are apparently not that impossible!

    Knew about Haemoglobin and Haemocyanin, but never heard of the other two before. Very interesting.

    Also, RIP Penis worms. Got a terrible name and have low efficiency oxygen transport.

    I knew about the hemocyanin because I was trying to figure out if one of the characters in my tentacle porn should have blue blood but decided against it. Cool to learn about the others too though.

        Nah. Weirdly enough it was the character with the arthropod features I was investigating the concept for but now I wonder if I should’ve done that for the illithid so I might look into that. It was relevant to the other character because the actual arthropod features (wings) are missing by the time of the story so it was going to be one of the “hints” that they had her labeled as the wrong species but first of all it just didn’t fit creatively, it was much too overt to the extent it didn’t even make logical sense for the mixup to happen but also as you see here the science doesn’t follow either it’s only spiders and the like that have it, not dragonflies.
