Animals Working Together: Crash Course Zoology #10

[@SpiderdayNightLive]

TIMESTAMPS FOR SPIDERS/ARACHNIDS 1:21 -> 1:31 Several, animated (intro) 4:52 -> 5:02 Two, real (two male jumping spiders fighting/intimidating each other) As a spider scientist (and the science consultant for CCZoo), I love these wonderful animals, but I realize that being startled by a spider can be scary (even if you like them!). An important part of overcoming arachnophobia is building positive interactions with arachnids on /your/ terms, so hopefully this helps some of y'all do so and enjoy the videos.

[@EdaugEthanbYT]

What does the CC in CCZoo mean?

[@percygallagher922]

Thank you so much! Spiders make me incredibly anxious (real a lot more than animated) so it's fantastic that you've done these time stamps so I know when to look away and can watch without worrying about a spider jumping out at any second.

"I'm hank green and this is crash course philosophy " OMG brilliant 😂😂😂

[@austinfreyrikrw6651]

"...just kidding, I'm way younger than Hank"...ouch! hahaha

[@wurzelgnom5760]

Maybe someday crashcurse will become a collective organism... then they all are hank green....

[@abramrexjoaquin7513]

@@wurzelgnom5760 every Scientific teacher is called "Hank Green" from now on. Like calling scie.teachers "Mr.Wizard" in the 50's to 60's.

[@ronaldtan7172]

me listening to this in the background and have to switch back to the tab, because what did i just hear

[@happyslapsgiving5421]

I was *NOT* expecting to see an animated Mr Green puking on Dr Wynn-Grant.

[@euchale]

Question: How is a colonial organism different from an organism that has various organs? Like in humans liver cells and brain cells are fundamentally different, even though they share the same DNA, however, they are not considered a colonial organism, unless I got that wrong.

[@AngadSingh-bv7vn]

This is my new favorite crash course

[@ryanb9749]

My favorite is chemistry because it helped me decide to quit college 😆

[@sirBrouwer]

I thought that the video would go in on non relative animals working together. like birds that ride on top of elephants.

[@Danial-pn2lq]

The funny thing is that these courses seem to be designed for kids but I bet most people watching them are adults LOL. Great content!

[@nickc3657]

This was great! I’m surprised you didn’t mention naked mole rats though. They buck the idea that only small or “simple” organisms can be eusocial.

[@ssotkow]

3:41 elephant caravan. The calves are so so adorable.

[@achimernest7656]

Don't worry Hank Green, 😉 1:12 you're not that old. 😆

[@TheNivKo]

Rae is really delightful :) thanks

[@ArifRWinandar]

5:33 Alan!

[@Vanillastump]

Gonne be totally honest, I was expecting this episode to focus on symbiotic relationships.

[@RehanRC]

Thanks for making bats even more horrifying.

[@crashcourse]

You're welcome! 🦇🦇🦇

[@mad_max21]

Hey, it's cute that bats share blood to sick relatives. They're like us. But you know, blood.

[@fidazalfa4767]

"So is the zooid or zoon the animal?" "Yes"

[@goldentrout4811]

You're a good host.

[@muhmalikali]

Philosophy and zoology? It seems interesting. My suggestion is to invite Hank Green to this show.

[@scheimong]

Lol I was confused for a moment when you said Hank Green

[@katrinarobinson1037]

Rae's hair is so pretty!

[@sonorasgirl]

Do the vampire bats only feed relatives? Genuine question, cause I thought it wasn’t based off of genetic relationships, but I might be 100% wrong here

[@bobbysanford4777]

Wow amazing! I certainly do not regret this course.

[@belogpolos]

As South east asian who is not familiar enough with american names, I really thought you have the same name with Hank.

[@TheN0odles]

Great presenter. Lol Hank Green

[@djnobles8548]

I too am Hank Green

[@CommieHunter7]

I am Hank Green

[@carlosdrfx]

We live in a society.

[@ancientswordrage]

Today me social, tomorrow eusocial

[@SpiderdayNightLive]

now you're thinking with kin selection

[@seanamato3279]

New Hank is best Hank

[@JV-km9xk]

If the naked mole rat is eusocial, then explain the one from kim possible. Checkmate zoologists.

[@charlieskerry-wallace9514]

I feel bad for the person who had to animate Hank Green throwing up.

[@LowellMorgan]

I was way too high for the beginning of the video.

[@oldcowbb]

wait, hank made another channel?

[@shomailakhan3411]

Great course

[@TheMemesofDestruction]

Bees 🐝 ^.^

[@1.4142]

So animals have memes too.

Do the bacillaria...

[@capivara6094]

But what's the difference between a colonial organism and a regular multicellular organism?

[@lakrids-pibe]

Don' get help from Hank Green when you have the flu.

[@CommieHunter7]

Siphonophores are one of the wildest colonies. I still have a hard time grasping how many differentiated animals end up combining in such a patterned way to create a larger organism.

[@masontrudgeon8085]

Me who went back just to make sure I heard the name right lol

[@GeraldBlack1]

Love it

[@theserpentofmendes]

A bit disappointed Kropotkin didn't get a mention.

[@ssotkow]

Herd mentality of tribalism must be like vestigial traits. Useful for our pack's survival in the past, now misfired and toxic within societies.

[@sabrinashamme9419]

Staying up late at night pays up when you get a new video from crush course

[@CrazyCarsSayara-1]

Good

[@sharada7111]

please do crash course politics/political theory! i'm begging you! you guys would be brilliant at that!

[@skilltreebusybee]

But in the case of the bats behavior they feed the young as a group all moms feed all young. It not naval it's with in typical behavior. Also note there safety in numbers and higher the average quality immune response the likely hood for recovery makes the bats care taking treats stitsicly beneficial because of the sick bat recovery rate and the blood transfer increases exposure to fungal and bacterial that might increase recovery through immune sharing I would loosely suggest that all multi cellular organism development as colonial until they are able to reproduce the group as a whole. a fungi genetic symbiosis is more likely to behind the growth of nervous system as a symbiotic process with a host cell and virus might have bin the Original jizz and the DNA cell the egg I mean 🤦‍♂️ theres more technical details here. but I'm just describing a system of not the steps

[@stax6092]

Cool.

[@jesper112183]

You can add arachnids to the list of animals that engage in social behaviors

[@Jay-ho9io]

So weird.

[@MrJ1GS4W]

That’s gotta be a Portuguese man o war in the thumbnail

[@rparl]

The Buggers (Formics) in the Ender series are for the most part, highly colonial. But occasionally a member would break away and have to be killed.

[@opeobiri3486]

[@penpineappleapplepen6574]

Wow

[@oldrapvids]

Helloooo

[@Red-in-Green]

Does anyone else read zoon as ZOOOOOON?

[@bri1085]

How aren't humans eusocial

[@DeborahFishburn]

Google says the two eusocial mamals (which were mentioned at the bottom) are the Naked Mole rat and the Damara mole rat.
