Tentacled Geniuses: Evolution of Octopuses, Squid and Relatives 

OH MY GOD! A DOCTOR POLARIS VIDEO WITHOUT A SINGLE "SMALL, CIVET-LIKE ANIMAL"!! WTAF????!!!!!?????!!!!!!!??????

Cephalopod ink can be used as a smoke screen, but more often a squid or cuttlefish will use a blob of ink as a decoy. They will eject a blob of ink while simultaneously changing color and taking off 90 degrees to their former angle of travel. You can even chase a cuttlefish, knowing that it's going to pull this trick on you, and still be fooled every time!

I always found it kind of messed up that octopi are that intelligent, yet two years is old as dirt for them. Ammonites could definitely be their own video since there were so many of them.

A phylogenetic tree to visualize the relationships among the various cephalopod groups would have been really helpful. Otherwise a great video!

one of the best scenes of Prehistoric Planet was seeing all the different types of Ammonites that lived during the end of the Cretaceous alone and knowing how diverse Cephalopods where during prehistoric times. I would love to see a similar sequence with Belemnites in a near future documentary.

YES! More invertebrate videos! There are so many amazing prehistoric molluscs, insects, arachnids, echinoderms, cnidarians, etc. to cover that it would be great if you could continue this! Can’t wait to see Dr. Polaris cover the evolution of flies, wasps, eurypterids, horseshoe crabs, solifuges, scorpions, crinoids, sea stars, corals, jellyfish, sponges, and so much more!

YES CEPHLOPODS ARE MY FAVORITE ANIMAL

“He’s Squidward, he’s Squidward, you’re Squidward, I’M SQUIDWARD! Are there any other Squidwards I should know about?” Basal Mollusks: “Meow.”

Wonderful as always doc. Can’t tell you how much I enjoy these videos!

Imagine if they lived longer lives... if they weren't self-destructing cannibals.

“Another day, another migraine. Haha, mi-“ -Squidward Tentacles

I've always liked that you show things that are mostly unknown to the masses

Good video

Cephalopods: exist Internet Artists: "Well, I think we all know where this is going."

Woah an invertebrate video that's new hope that we may see more in the future

I’ve been looking for a video like this!

Keep up the good work 👍

12:11 I don't disagree but I love how you worded that as though it's just another objective fact about them

Fascinating creatures with sometimes great intelligence.

Bro this is cephlapretty good content

10:25 I read a study published like last week which describes a new species of vampire squid, so now there should be two living species, V. infernalis and V. pseudoinfernalis

Love cephalopods videos❤

You should make a video about the Aphaneramma, which is a crocodile-like genus, that are amphibians that swam the oceans. I love your channel and your videos.

Thank you very much for providing this interesting video!

This video is a......slice of octo pie 😁....anyway the good doctor continues to make the medicine ya didnt know ya needed.

Hey Dr.Polaris, right after the Cryptid called the Yowie, why don't you think about making a suggestion and creating a RU-vid Videos that's all about the evolution of and the history of the Prehistoric Marine Reptiles called the Plesiosauria, (Plesiosaurs, Pliosaurs, And Polycotylus) in the next couple of weeks to think about that one coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍

Hey! Happy to see the cryptozoology videos are coming back. Those are fun to listen to.

It amazes me that these beings have not developed adaptations for life in fresh water

I enjoyed your video so I gave it a Thumbs Up

Octopi are my favorite invertebrates, they are such weird and unique creatures. i think having one as a pet would be awesome but i hear they are pretty difficult to care for properly.

Such fascinating creatures

I’ve mentioned this before in Anthony pain’s video about squids and their evolutionary history, but the giant squid and colossal squid are the closest to an actual kraken.

You said octopi so I'll share a fact: the final i is used to make plurals in latin, but octopus is a greek word! The correct plural in greek is octopodes, while in English it's octopuses.

I had no idea there were that many described octopus fossils.

watching this while eating squid never felt so good

I always love your work, but where did you get the graphic at 4:17? Its style looks like professional textbook work, but it has two spelling errors in the first panel. Vamp-y-r-opoda (as in Vampyromorpha) and Vampyromor-p-h-a.

12:31 Ammonites 2.0? Hell yeah🐙

YEAAAAAAA FUCK YEA

Why is it called dumbo squid and not cuddlefish?

Not the beach episode

im gonna order some calamari tonight

"among the cutest of invertebrates" by what metric? you need to back up that claim with numbers😄

Sorry I seriously doubt that sea reptile at 6:00 had a snake tongue like that.

"I wish squids were real." -some guy on splatoon's chat lobby

Who said you need internal skeleton to be intelligent?

Cthulhu likes this video.

The Deep approves. 😅

Saddest animal in existence... Imsgine being so smart and having the ink but nothing to write on.

big hairy man, little hairy man the big one just grabs you the little one its said has strange powers to entrance but what would i know I a gubarorginal

New video

🐙🦑👍😊

thanks for this! but making a cryptid video seems like a waste of time ...for everyone involved

are you ok? what's up with your voice

the plural is octupuses or octopodes, never octopi!

It is NEVER octopi! Octopus comes from the Greek so Octopuses or octopods!

Tch, OctoPODES.

1st

What do you get when you cross a Giant Squid with a Trump supporter?? Archetoothless!!!😅

Hail our great and dearest President Lula!

Hey Dr.Polaris, right after the Cryptid called the Bunyip, why don't you think about making a suggestion and creating a RU-vid Videos that's all about the evolution of and the history of the Prehistoric Marine Reptiles called the Plesiosauria, (Plesiosaurs, Pliosaurs, And Polycotylus) in the next couple of weeks to think about that one coming up next?!⭐️⭐️⭐️⭐️⭐️👍👍👍👍👍
