i love when people have the ability to make me feel so engaged in something i never realized i would be so interested in

[jopo]

His presentation style is so smooth.
He didn't flounder once.

[binry_dstructr]

Okay, the mantis shrimp boiling water to exceed the temperature of the sun's surface is literally the craziest motherfxxking thing I ever heard.

[callmemyss]

OMG Kory that's my fraternity brother glad to see he still doing his thing with Marine Biology 😊

[cat-ucqx]

As someone who got their degree in Marine Science, this makes me so happy. Yes, I knew the answers, but this guy is so hella charismatic, I felt like I was learning something new. And, as someone who also specialized in studying fish for graduate degree programs, it's also a joy to see a lot of fish-based questions. Fish are, no doubt, the coolest group of organisms on the planet.

[lilianaabramson]

Thats my professor!!! Omg!!! Absolutely loved his class last year, definitely one of my favorites I've ever taken!

[visualcipher]

a literal shrimp creating heat as hot as the sun by punching water, my lord.

[Mustlovebooks]

I could have watched a couple hours of this guy answering questions. He explained enough without going overboard or racing through and not really answering. Super interesting.

[FormerlyAVM]

“Fishes” is the most amazing thing in this video. 30 years and I now know it’s fishes, I’m shook.

[Melvin-ntxu]

The description of a Mantis Shrimp is like a Pokémon Pokédex entry

[Gavrilo-wwnd]

BRING HIM BACK. MORE VIDEOS WITH THIS GUY.

[Mathematics]

"No google needed" was so cold

[dennisbrown]

I imagine them putting on the hat and saying “LoOK iM a hoOMAN” and all the other orcas laugh hysterically

[cookiemonstaaa]

Loving seeing POC drs and scientist, thanks for bringing them on

[jesnoparat]

All of this is so very fascinating. He really knows his stuff and is such a great communicator, which is so so rare. Great video!

[bluebestfriend]

Guys, "Fishes" is correct. The only time "fish" is used in the plural is when you are referring to many of one *kind* of fish. (Which is what we do normally). It is "Fishes" when you are referring to the entirety of the paraphyletic group.

[sz]

I love when an expert so clearly love their field. Super interesting stuff

[ProfessorRainman]

Definitely more of Dr. Kory would be awesome, WIRED!

[stopthecap]

I have never once been interested in marine biology, I've watched these kinds of videos about specific jobs I am super interested in, and yet this is by far the most interesting and best one I've seen.

[yryr]

Hits blunt. Yes please continue my good man. I love this
