  • Here we will explore true facts about the Octopus.

  • Deep in the depths of the ocean, lives a marvelous creature

  • sometimes referred to as the floppy-floppy spider of the sea.

  • But it's true name comes from a Greek word

  • meaning "eight-footed"... because it has eight arms.

  • There are two major suborders of octopuses:

  • the Cirrina and Incirrina.

  • The Cirrina octopuses look a bit look like

  • an alien got freaky with a weather balloon!

  • They have two little fins, a small internal shell

  • and lots of little cilia next to their suckers.

  • The other suborder, which we will be looking at today,

  • are the Incirrina.

  • No internal shell, although some do try to fake it.

  • No fins, but 100% amazing.

  • Many of you will know the amazing color and texture

  • changing capabilities of the octopus,

  • as well as its ability to fart ink at a moment's notice.

  • Evolution at its finest.

  • However, perhaps the most remarkable feature

  • of the octopus is its intelligence.

  • They are the most intelligent of all the invertebrates.

  • Technically, not tons of competition there.

  • I mean, clams are stupid. I'm sorry, I said it.

  • But they are dumb as hell.

  • What is amazing is that while octopuses can learn

  • and remember complex tasks like opening child-proof jars

  • and moving through mazes, they are using an intelligence

  • that has evolved very differently than our own.

  • Unlike our intelligence, which is mainly centralized

  • in our head hole, the octopus has distributed intelligence.

  • Three fifths of all of its neurons are located in its arms.

  • In a way, each of its arms actually has a mind of its own,

  • which is amazing...

  • unless, after a while, you found out

  • that one of your arms was an asshole.

  • That would suck.

  • These arms are so capable, that even when they are severed,

  • they will continue to search for and capture food!

  • And then try to bring that food back to a non-existent mouth hole.

  • Some octopuses will actually remove one of their own arms

  • when threatened and let it wriggle away

  • to confuse the hell out of predators.

  • Data point of one, but it would confuse the hell out of me.

  • Each arm of the octopus is equipped with over 250 suction cups,

  • each one with the ability to rotate and grasp independently.

  • Not only are they grabby grabby,

  • but the suction cups contain sensory receptors,

  • which allow it to taste and smell what it touches!

  • This is an ability I'm glad I don't have.

  • It is widely known that the interestingness of an animal

  • is proportional to how difficult it is to figure out

  • where its butt hole is.

  • The octopus is, therefore, very interesting because its mouth

  • is exactly where I thought its butt should be.

  • I'll be honest with you, I still don't really know where it is.

  • But my search history does contain the phrase

  • "Pictures of an octopus' butt."

  • Inside the octopus' mouth is a beak, the only hard part

  • of the Incirrina body, meaning that the octopus

  • can squeeze through any hole larger than its beak!

  • The tentacles guide food towards the beak,

  • where venomous saliva incapacitates prey

  • before the horror begins.

  • I told you. Clams are stupid.

  • When it comes to moving, the octopus has a variety of options.

  • It can crawl or use a water jet called a siphon.

  • Or it can do this! (chuckles)

  • Which is my favorite. (chuckles)

  • Some scientists have argued that two of its arms

  • should be characterized as legs!

  • I wonder why. (chuckles)

  • They can walk! (laughs)

  • Octopuses can even move on land quite effectively.

  • Yes, they get a little mushy on land, but don't judge.

  • It's like reverse shrinkage.

  • Imagine what they think when we skinny-dip.

  • "What happened to your little arm?" That's what they say.

  • Although the octopus' eight arms may seem identical,

  • one of the male's arms is actually hectocotylus,

  • which functions like a penis.

  • Therefore, shaking hands with a male octopus

  • is sort of like playing Russian Roulette.

  • But instead of dying, you risk your hand getting pregnant.

  • The hectocotylus is used to transfer spermatophores to the female,

  • either by inserting it into a hole in her mantle,

  • or by tearing it off and presenting it to the female for later use.

  • To understand this, imagine if you are on a date

  • and your date reached down and...well.

  • That is how an octopus do.

  • To the octopus, human sex looks really, really boring,

  • like we're just saying hello to each other.

  • Because when they get it on, it can get crazy!

  • When the female has fertilized her eggs, she retreats

  • to an underwater crevice and attaches her eggs to the roof.

  • She will stay with them, gently blowing fresh water over them,

  • protecting them, as she slowly starves to death.

  • Basically, everything they do is hardcore.

  • When her job is done, she is gone,

  • but thousands of little babies emerge, floating.

  • Just beautiful.

  • Sort of like the ending of Charlotte's Web, except underwater.

  • Without the farm animals, too. They would all drown.

  • They would die.

  • The dancing pig wouldn't last a second, really.

  • It'd be babies interspersed with these dead and rotting animals

  • being eaten by fish. It's a different story, really.

  • Less appropriate for children and I--

  • the duck would do okay, but one floating duck

  • does not a children's book make, you know?

  • Just remember, if you're writing a children's book,

  • one animal can die. Not all of them.

  • Only a clam would write that sort of crap.

  • But they're dumb as hell.

Here we will explore true facts about the Octopus.
