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?
Highest to lowest. I edited it into the comment.
- obligatory Homestuck mention *
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.
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.
Don’t dip your oar in Lake Katchakootie
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.
Penis worms?!?!
interesting to know there’s purple blood, though! I didn’t know that
Whoever named the penis worm hit the nail on the head.
I see what you did there
Haha they’re called like that because of their shape right? Right?
