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 6 months 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 6 months 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. 👍🏼

Did you go with purple?

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

Penis worms?!?!

interesting to know there’s purple blood, though! I didn’t know that

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.
sudoroot@lemmy.zip 6 months ago
My exact thoughts. Penis worm? Time to look up how to actively avoid getting any penis worms.
loaExMachina@sh.itjust.works 6 months ago
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.
