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. https://en.wikipedia.org/wiki/Priapulida?wprov=sfla1
You’re right. It’s the Sounding Worm that is the penis parasite, not Penis Worm. Sounding Worms are aptly named because they get inside the urethra and live there, and can even cause orgasm when excited.
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.
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!”
This is yet another trick to make us look at penis worms :P
