Octopuses Have 9 Brains, Three Hearts, Blue Blood, Turn Invisible, Can See With Skin And Die After Having Sex

Octopuses have nine brains — one central brain, eight at the base of each arm, for movement control. Two-thirds of an octopus’ neurons reside in its arms, not its head. As a result, the arms can problem solve independently of the rest of the body.

They can navigate through mazes, solve problems, take things apart, and remember solutions.

They have blue colored blood due to a protein called hemocyanin.
Octopuses evolved a copper rather than iron-based blood called hemocyanin, which is more efficient at transporting oxygen than hemoglobin.

They have three hearts. Two of the hearts work exclusively to move blood to the gills, while the third keeps circulation flowing to the organs. The systemic heart is inactive while the animal is swimming and thus it tires quickly.

A 50-pound octopus can squeeze through a hole only 2 inches in diameter. If their beak fits, they can get through. They are about 90 percent muscle.

But even stranger:

  • Octopuses die shortly after mating.
  • Once a male provides sperm to the female they wander off to die.
  • Females lay eggs and when the eggs hatch, the female’s body undertakes a cascade of cellular suicide, rippling through her tissues and organs until she dies.

They can hide in plain sight
Octopuses are difficult to spot. Their skin changes color and pattern to blend in with their surroundings like a mirror. Even when you find yourself looking directly at an octopus you may not see it.

They can “see” with their skin
Octopus skin contains the same light-sensitive proteins present in octopus eyes.

  1. Interesting. Octopuses are an interesting species for sure.

  2. That is fascinating! I’m particularly taken by the “blue blood” from the hemocyanin protein. Reason? My Teachers told me that a race of aliens who for a time colonized part of Earth had blue blood. Some of them had intercourse with their cloned human female slaves who in turn gave birth to “blue bloods” or the first superior human race, the so-called Nephilim (also called giants) who became rulers over mankind after their wars against their alien forebears (the Anunnaki as known to some) had pushed them off the planet. The term “blue bloods” continued on down to our times as those who believe themselves to be divinely instituted royalty with a natural right to rule. Unfortunately for them, the real blue bloods (if any are left) are a weak mutant race with a poor immune system. Perhaps the octopus’ strange death process is linked to that… just thinking out loud. Thanks for making me do some more thinking in an area I find engrossing.

    • You stated — “Unfortunately for them, the real blue bloods (if any are left) are a weak mutant race with a poor immune system.”

      My response — That’s interesting because there is a race of people alive now with blue skin described as weaker and due to mutation.


      You stated — “…who became rulers over mankind….”

      My response — This is also very interesting.

      “The Cecaelia is a creature with origins in Asian and Native American mythology, legend and folklore. In particular, accounts of their existence are first recorded among such cultures as the Haida, Tligit, Tsimshian and Nootka tribes.

      Among these, the Native Americans seem to attribute a certain connection between the Octopus-People, and the Raven People.”

      There was also that strange scene in Hell Boy that talked about ancient beings from space that looked like octopuses. It stated that they were the ancients and mankind once worshipped them or something like that. It stood out to me because I had never seen anything like it in other movies.

    • You asked — “That is fascinating! I’m particularly taken by the “blue blood” from the hemocyanin protein. Reason? ”

      My response — It allows them to get more oxygen faster in colder deep waters.

  3. I had heard about the three hearts from “Finding Dory”. I hadn’t known about the rest. BTW, octopuses is grammatically incorrect. It should be “octopi”.

  4. Wow. Knew about the 3 hearts (due to watching “Finding Dory”), but not the rest.

  5. Enjoyed the video and the music.
    I saw a few octopus while scuba diving in Hawaii.
    They are very talented at squeezing into and popping out of small spaces.
    Took my breath away when they would suddenly appear before my eyes.
    Didn’t know they had 9 brains. Way smarter than me!
