Blue blood may be cool, but red blood is better for you.
=> Nobility is fashionable, but it’s healthier to be a peasant.
Also, from this table I learn that Europeans of ages past were ruled by octopodes.

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?
neidu2@feddit.nl 3 weeks ago
Highest to lowest. I edited it into the comment.

This is yet another trick to make us look at penis worms :P

Well “hey baby wanna look at something purple and full of blood” hasn’t worked for me yet

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

Yeah one of the great lies we were all taught.

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.

Many of the comments being “penis worms!”, but no one is asking about that Red blood is only in the “majority of vertebrates” leaves me wondering which vertebrates have what other colour(s) of blood.

Whenever I see this image I always wonder 2 things:
- What makes hemoglobin more efficient?
- Why do we even need these fancy molecules to transport oxygen? Can’t we produce some kind of biological ampule that holds some pure O2 for consumption by the various processes that need it? We have dedicated organelle structures for similar tasks (i.e. mitochondria)

- Penis worms?
InverseParallax@lemmy.world 3 weeks ago
-
It’s sensitive to pH, so it absorbs oxygen more readily in the lungs, and releases it slightly more near tissues that need it, as they have co2 which slightly acidifies the blood in solution (h2co3).
-
It’s effective and well tuned for our biology, it doesn’t bond strongly, and is well suited for the air-blood interface, unlike others that often favor water-blood or water-the fluid worms use instead.

Thank you. Clear, easily understood explanations of questions I always wondered. 👍🏼

CO2 and H2CO3 (apparently I don’t know how to do subscript on here.

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.
alcoholicorn@lemmy.ml 3 weeks ago
Did you go with purple?
Apytele@sh.itjust.works 3 weeks ago
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 important for 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.

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

Guys, the blood that’s coming out of my penis worm is red.

Oh neat, now I know Penis Worms have purple blood. And that Penis Worms exist.

My exact thoughts. Penis worm? Time to look up how to actively avoid getting any penis worms.

Chill, they’re called that because they kinda look like penises, they’re not penis parasites. en.wikipedia.org/wiki/Priapulida?wprov=sfla1

They’re easy to spot if you have them.
They’ll appear as thin squiggly lines running underneath your skin, usually a different pigment than your natural skin tone.
