I only learned this thanks to Google when I was learning about how we use horseshoe crab blue blood to test that IV drugs and implants are hygenic enough for human use.

Hmm, I thought an Octopus had green blood

And 9 brains

My favorite crazy, unprovable theory is that octopi are aliens that dropped into the ocean from an asteroid or something. Ridiculous, but also octopi have three hearts and blue blood.

Because the limbs are technically brains too?
ShaunDark t1_jdyvxog wrote
No, because each limb actually has a little brain inside it. And a central one in the head

They also have 9 brains. NINE.

In Hawaiian mythology they are meant to be basically that if I remembering correctly, universe renewed but they survived, alien survivors from a prior cycle.

The main one of which is wrapped around their esophaguses. Ergo, if they don’t chew thoroughly enough, they may easily sustain brain damage.

And they are busily constructing their forward operations base deep in the ocean to wage an invasion when the rest of their fleet arrives from Betelgeuse.

Everyone has blue blood it just turns red when it hits the air. I and everyone I went to school with believed this as a kid for some reason

Well, there we go. Very believable, I think.

Anatomical diagrams have arteries in red and veins in blue for easy identification.

When an arm gets severed (which the octopus can regrow), it hangs around for a bit, doing stuff, trying to feed a non-existent mouth. Kinda sad tbh.
Also, male octopuses have a special arm they use for mating. In some species, do avoid sexual cannibalism, they have developed a strategy of ripping it off, upon which it swims on its own towards the female to impregnate her. We live in a world where there are sentient penises swimming around and seeking to mate.

Pretty sure that it's provable that they are NOT aliens.

My health teacher told us it was blue until it hit the air. I don't think her degree was in a science, haha.
