Why (only) some Sharks are Warm-Blooded

Sharks have the reputation of being cold-blooded killers that will attack and try to eat just about anything. But in reality, they are actually a lot pickier than many people realize - Attacks on humans are very very rare. But even the "cold-blooded" portion isn't even true - at least not when it comes to Great Whites. Because they are in fact part of a small group of sharks that can elevate their body temperatures above the water temperature - effectively becoming warm-blooded. Here's how they do it.

Thanks for watching.

Part 2 will be released in 1-2 months. For now, I wanna do other topics.
Also: This is one of the first videos where I didn't cover a story (so to speak) but more of a scientific concept, which required a more minimalistic animationstyle. I just hope it wasn't too dry.

1:35 Ahahhaha the roblox death sound caught me off guard

The "OOF" wins my "seal" of aprooval

Will you do a video on how Bull Sharks can survive in fresh water?
I'd like to know about it.

Wonder how many comments will be about the roblox oof noise.

As a Chemical Engineering student in university, learning about how nature utilizes heat/mass exchange systems is just fascinating! It really opens your eyes to the various applications of the theory I’m learning and the industrial heat exchanger systems that are so vital to many industrial and factory settings.

Truly an eye-opening video! I’ll email it to my professors and maybe they’ll even show it in class next semester!

2020 and the second part still hasn't been released. Kinda sad, it really was an interesting topic.

[LordOmnissiah]

Interesting, but what happened to Part 2?

[tracybowling]

I can tell you/your team worked really hard on this video. It is very easy to watch and very interesting!

[Swimslikefish]

This video is so incredibly well done, the easy and understand graphics and the outstanding explanation to compliment this complex topic, 10 out of 10! This is what this site should be!

Ducks have a counter-current heat exchange system in their feet, which is how they can swim in near-freezing water with warm feet and avoid tissue damage.

When tuna are caught, they're thrown into ice immediately because the high temperature of their metabolism will end up cooking the meat.

1:35 if this isn't enough reason to call you one of the best YouTubers, I don't know what is. Fantastic work as always!

Great White: Changes from cold to warm bloodedness

Nature: Am I a joke to you?

[sebastiangoddard]

These must be so great to make! Diving in-depth into whatever topic tickles your fancy is the best way to study. Keep up the impressive work

YouTube needs to get rid of the 10 minute rule. So many youtubers are forced to add filler to their videos and it’s really annoying for everyone BUT YouTube.

[meow]

Your videos are so incredibly well made man. Thank you so much for focusing on high quality content!
