It's honestly kind of accurate. Vomiting involves the muscles of your esophagus working backwards to push your stomach contents out (which is not what they're usually doing, and hence why you often feel sore after vomiting).

You managed something that I thought was impossible: you managed to 1-up your own video about sea cucumbers which was already excellent!

[@DanGamingFan2846]

I've been waiting for this ever since you briefly touched on them during the sea pig video. They're such fascinatingly weird creatures. Also, "Take that you asstropod!" Hilarious.

[@medicwebber3037]

I think this was one of your best! Soooooo many good lines AND absolutely fascinating!! Thank you!

[@CritterHunter]

This is one of the most amazing educational lessons I have ever had. Its audience will appreciate how exquisitely written, smart, and flexible it is. Kudos to you!

You are an absolute genius and a treasure to have on KZbin. The "teaching" ,or child friendly versions let me share your style with my nieces. We love all of your content

This episode got a few really good laughs out of me. Im so happy this series is back, I feel like I'm 12 watching the anglerfish episode again

[@danielleking262]

The ostrich one and the marsupials video ALWAYS crack me up when I need a good laugh. 😂

[@mayhemmcfly4229]

Also the Nudibranchs. "Imagine performing a 4 way high five..but using your genitals.." I nearly died with that one.

[@MEGAMIGA]

Personally, I love the carnivorous plant one!

[@samanthasimiskey5288]

ZeFranks' videos never cease to amaze. He could do a whole series on the common trout and I'd be repeatedly watching each one. Incredible

By far the BEST narrator and writer on you tube! I don’t even like half the subjects but I listen to them completely because it’s so amusing and smart and just thoroughly entertaining. Kudos.

[@TF2CrunchyFrog]

As a biologist (albeit an ecologist, not a marine zoologist) seeing sea cucumber species I'd never seen before and sea cucumber body plans I didn't know existed in those shapes was a thrill. Hard to tell some of them apart from nudibranches at first glance.

Why have I not seen this guy before?? He's both educational AND hilarious! This is how education should be taught, not by boring your class/audience, but by making it both interesting AND funny! We'd LOVE to learn every day if stuff was represented this way for any and all subjects!

You've only just discovered the WONDER that is ZeFrank?? Congratulations! You have sooooo much lovely binging to do!

[@chubmouse6458]

Man, your writing is always incredible, but this one has been particularly hilarious! I think it's often understated how amazingly humour works as a supporting element when teaching, especially with how well you integrate it into the actual facts without breaking the flow and how everyman they are, nothing intentionally flying over anyone's heads, because "Ass+" and "looks like how it feels to vomit" have taken up long-term lodging in my skull for the foreseeable future. Brilliant work! And the sponsor of today's video...

So, when I was a tiny thing, maybe 8 years old, my class went on a fieldtrip to the aquarium. There, we learned about the sea cucumber, and how it can "throw up its stomach." But we were also told that kissing a sea cucumber *without* it throwing up its stomach would give you ten years if good luck. Long story short, when I was 8, I kissed a sea cucumber in front of all my classmates.

LMAO I didn't expect this much interest. The sea cucumber was a perfect gentle-creature, and kept its insides inside. But I think the ten years of good luck were delayed, cuz those didn't hit until a few years later. :p

Through tears; note to self: While laid up recovering from two broken ribs, no matter how exited you are to see a new Zefrank video (yayyy!) do not watch it yet. Just, be kind-er to yourself and save it until later.

Ow! Seat belt broke them in an accident or you got kicked by a horse? Or just good old kicked by a human?

Maybe it was the... MURDER CHICKEN 🐔. Sam Nelson I hope you feel better, broken ribs are difficult, can't be immobilized like other bones. Hug a pillow if you can't help watching Zefrank😂. Laughter is the best medicine but in this case it comes with side effects. Feel better!

Most things that brought joy 1-2 decades ago don´t even have a dark corner in my memory anymore but for some reason zefranks work is so good that I find - for example - this episode to be even better than some that came before. Weird thing is I think that about every episode.
