That's right, you found it. Curiosity Daily from Discovery. We are here and ready to help you get

smarter in just a few minutes. My name's Nate.

Welcome back everybody. My name is Callie.

We are so excited to have you here with us today at Curiosity.

Today you'll learn about the incredible dynamics that make the Thresher Shark so good at Threshing,

how people with a rare growth disorder might actually have an

advantage that leads to longer lifespans, and why people listen to sad music.

Neat, let's learn some stuff.

Shark Week is upon us, and I for one have been dipping my toe in the Shark Week waters and so far have not been disappointed.

Psh dipping your toe, come on, I'm fully geared up in the Shark Week Shark Cage. Can't get enough. I have been glued to my TV since Sunday.

Okay, well then, one shark you might recognize is the iconic Frusser Shark.

Oh, absolutely. Their silhouette is something out of prehistory with you know they got the long sharp tails and their grace in the water they're almost ghostly I agree wholeheartedly they are among my favorites and those long with like tails can be as long as their entire bodies and without them

they'd actually probably go hungry. Unlike most sharks that stock and approach their prey head on,

threshers close in on their prey and then they actually thresh them with those tails.

All right, the threshing stuns the prey which allows them to gobble it up.

And that stunning motion is not only pretty unique, it's super effective.

Threshers can attack and consume schooling fish like tuna, mackerel, and squid.

And tuna is like the Ferrari of the sea, so it's no easy task.

But one thing that has caused some debate in marine biology circles is how that

tail works.

I mean it seems obvious, it whips around and stuns the prey.

Yeah, but what is going on inside that tail?
