This summer, ditch land.

With shortwave's sea camp, because when's the last time you had an ocean getaway?

Every Monday, we bring you in sites from a different ocean zone, starting with the sunlit surface until we hit the deep sea floor, where there's marine snow, weird critters, carbon sinks, and so much more.

But first, you've got to take the plunge.

Remember those science class lessons where we learned every ecosystem is a delicate web,

and even the smallest disruption can send ripples across the planet. Turns out, those food webs are even more fragile and fascinating than we realized, especially

when it comes to sharks.

For this Shark Week episode from Discovery, we're diving into the science of cascading effects

and why sharks are such a critical piece of the puzzle.

We'll kick things off by exploring how sharks migrate in unexpected ways.

Then, I'll sit down with shark scientist Alison Towner for an insider's look at great white shark research,

especially what's happening to these apex predators off the coast of South Africa.

And before we wrap, we'll decode what the blue label on your seafood really means for sharks and the health of our oceans.

So grab your snorkel. Our second episode of Shark Week starts now.

Thanks for joining me on Curiosity Weekly. I'm Dr. Samantha Amin here to guide you through the latest curiosities from the world of science.

There's no place like home. There's no place like home. That famous line Judy Garland said in the Wizard of Oz, it's actually something great hammerhead sharks live by. Well, some of them, that is. Great hammerheads are critically endangered. These sharks grow slowly. They have few babies and are super vulnerable to overfishing. Their global

population has dropped by more than 80% over the last few generations. That's not great. So if we

want to save them, and we do, we've got to figure out where they like to hang out and when.

There are some that like to take long distance ocean road trips, and then there are others who just want to be home like Dorothy. A team of researchers found a group of hammerheads that really don't like to travel far. Their home is in the clear turquoise, cobalt blue, and teal saltwater off the coast of the biggest island in the Bahamas, Andros Island. These hammerhead sharks aren't migrating

up to the east coast of the U.S. like many sharks in the region do. They actually stay put in
