The Insane Biology of: The Octopus

I gotta go to work in 4hours and I'm over here learning about octopuses at 2 AM

"You gained intelligence?" octopus: "yes" "What did it cost?" octopus: "shell"

I worked with a marine biologist studying cephalopods. He had one big tank for octopuses and one for crabs, their favorite food. One morning he came in and found that one of his octopuses had pushed the lid open on his tank, crossed the floor and climbed into the crab tank. Soon it became a common occurrence. He decided to give the octopus a mild shock when he found it in the crab tank to deter it. Within days he came in and found the octopus had still gone to the crab tank, eaten it's fill, but then climbed back to its own tank to avoid the shock. They are amazing animals.

I hope there is an updated version made. Octopuses and squid are now known not to be colorblind but just as their intelligence evolved differently than chordates their color vision is completely different. They only have a single type of photodetector and the fact that lenses are achromatic and have non-circular pupils and their visual system is much more complicated than ours so as to be able to extract color diffraction around the edge of the pupil and the achromatic distortions caused by lenses.

Having done a lot of diving - I can say that the octopus is an absolute marvel to encounter. Some (mostly the younger ones) are ... So curious. At first it's like "WOW! U THREAT?!" once it establishes that you are not, it's like "Eeer ... What are you then? I've never seen one of you around before." and there begins the act of mutual curiosity :3. You slowly reach with a finger, it sends a tentacle ... you both touch, sometimes they get frightened and clamp your entire hand, flashing black before letting go, but not swimming away. They are playful, find a shiny pebble, hand it to the octopus, it'll take it, check if it can be eaten ... discard it ... then a few sec after send a tentacle back to the pebble out of curiosity as to "why did he give me this pebble ... gotta check again for anything special". They really hold a very special place in my heart, it's not everyday that two species get curious about one another and attempt mutual understanding :)

just how intelegent are they? octo : wearing coconut shell while walking like a model

> ditched the shell > evolved intelligence So this is what it means to leave your comfort zone

Such content is incredibly underappreciated

Ever since I was 8 years old, I've wanted to be a marine biologist. I would always wonder about all these amazing creatures that are found in the ocean... My parents wouldn't let me have my own phone, so I would ask them if I could watch a video on their phone about sharks and dolphins and all marine animals I could think of. My cousin is currently in university studying to become a marine biologist, and she lives on the opposite side of the world from where I do, yet every night, we talk about these mysteries of the ocean through messages. Although I am still in school and still have many years of school and high school, I still want to be a marine biologist. These videos of the ocean makes me even more curios! Thank you for sharing this information.

Can we just appreciate the fact that there isn’t a single ad in this whole video?

changing colors and body textures is incredible but what amazes me even more is the speed at which the octopus does it…it’s freakin insane man

When you learn something so incredible and interesting that you feel like you need to go tell someone about it, you know you learned something good.

Man this reminds me of me and my dad watching late night documentaries about anything. Rest In Peace Papa

How is it still legal to EAT those creatures?

Octopus: holds out tenticle Diver: shakes tentacle Octopus: ...Damn these four legged seals are smart

The next time someone tells you, you need to get out of your shell; they’re offering you a path to evolution, intelligence and enlightenment.

“... as fast as the fastest blink you can do.” everyone: blinks

Millions of years from now octopi will be studying why humans destroyed themselves.

This channel inspires a sense of wonder about nature in me that I hadn't felt since I was a kid. Thank you so much
