Cephalopods exhibit some incredible features. Out of all 8,000 living species of marine invertebrates in the oceans, by far the largest, most deadly and most intelligent are the cephalopods. A class of highly developed mollusks that includes octopuses, squid, cuttlefish and the mysterious nautilus. Their graceful fluid movements, vibrant colour changes and complex brains make them one of the most peculiar and important groups of organisms in our oceans. The largest - the giant squid - measures longer than a school bus, while the smallest could sit atop your finger. Let’s take a closer look at these diverse and often alien-looking invertebrates.

I had a pet octopus that i found in a small puddle on a rocky beach. He was maybe 5 cm in size when i got him and have kept him for over a year in my aquarium. James (his name) was a very smart dude, he knew i went out every afternoon to catch crab for him because he would always be waiting in the front corner of the tank where i would drop the crab when i got back. He got rather big and i set him free when he was about 3 kilos. He liked to be handled and would hang out on my arm whenever i put it in the tank.

Imagine being one of the most intelligent creatures in the ocean only to be eaten alive in mukbang vids

Whenever I see a giant squid I get chills down my spine. The fact that something that large exists is terrifying yet beautiful in a strange way. I do however wish you went more in depth about the lesser known cephalopods like cuttlefish and nautilus, those things are just so interesting and diverse and I’d love to see what you have to say about them!

One reason why cephalopods are frequently depicted in the media as monstrous and menacing is because of their tentacled appearance, even though real life cephalopods would be passive when encountered in the ocean.

I never comment on YouTube videos but I need to this time. The quality on these videos is amazing. The combination of images, background music and narration is very well done. Sometimes the content or the length of the videos may not appeal to everyone or attract millions of views (yet) but the work done here is phenomenal and you deserve a lot of attention. Great work!

Man, this reminds me of why I wanted to be a marine biologist as a kid. Great production value on your videos, my dude! A small, but noticeable thing, is the appropriately-chosen music in these; the mysterious creatures have mysterious music backing their appearances, & it’s a subtle but meaningful thing that really reflects the feeling of living underwater...it’s such an alien concept, fascinating and frightening in equal measure to myself. Great work on your videos!

This channel is going places. From the production levels, to the information and it's delivery, all expert quality in my layperson opinion. Wouldn't feel out of place on the BBC. Keep up the amazing work, you've found a fan in me.

Oh finally a cephalopods video!! Those are the absolute best marine invertebrates :D Best part was about cephalopod bioluminescence and gigantism, especially because those are the most poorly known, mysterious aspects when it comes to fossil squids. It's also brilliant that you're putting the music in the description :) This channel's gonna blow up, I can feel it.

I just discovered your channel this past week when I was looking for documentaries on the ocean zones for a project. Your documentary Into the Abyss was amazing and I’ve been watching the rest of your videos whenever I can. Absolutely love and adore your content! Sending lots of support from Texas!
