  • Hi everyone!

  • Squeaks and I thought that it'd be fun to learn about the ocean today!

  • But to help us learn about life in the world's oceans, we've invited a few experts who

  • know a lot about the subject.

  • [Clicking and Clacking as the screen opensScience science science”]

  • Wyatt, Ned, can you please use your undersea voices for a moment?

  • We're going to talk to Jessi.

  • Hi everyone!

  • Oh!

  • Hi Jessi!

  • And hello audience!

  • I'm Dr. Irene Stenella, but you can call me Dr. Irene.

  • And these are my two lab assistants: Ned and Wyatt.

  • Hi!

  • Hi!

  • Thank you so much for joining us today to teach us about the oceans and what animals

  • live there!

  • Dr. Irene: Jessi, Squeaks, it is our pleasure!

  • First things first, let's look at the ocean.

  • The ocean covers more than half of the surface of our world.

  • And it's deep!

  • So deep that, in many places, the sea floor never gets any sunlight.

  • And in fact, we scientists talk about the ocean as having three different zones, and

  • we know which zone is which, based on how far sunlight can travel from the ocean's

  • surface.

  • Yeah!

  • Oh wow!

  • So the different zones are named according to how far light travels from the surface

  • of the ocean?

  • That is correct!

  • And the first zone is called the sunlight zone.

  • The sunlight zone goes 200 meters below the surface of the ocean.

  • That's about as far as two football fields, laid end to end!

  • Correct Ned!

  • And sunlight can rarely go further than the sunlight zone.

  • Wow!

  • So what animals live in the sunlight zone?

  • All kinds of animals!

  • The sunlight zone is warmer than the layers below it, and plants can grow there, because

  • the sunlight can reach them, which they can use to make food.

  • Because of these things, there's a /ton/ of life in this zone.

  • You can find dolphins, like us, tuna, sea turtles, jellyfish, rays, seals, as well as

  • seaweed, corals, sea anemones...

  • The list goes on!

  • Did someone say tuna?

  • Cause I'm hungry!

  • Ned.

  • Please.

  • It sounds like the sunlight zone is the place to be!

  • It is quite delightful!

  • Below the sunlight zone, there's the twilight zone.

  • This is where it gets dark really fast.

  • Sunlight sometimes reaches this layer of the ocean, but there's so little light that

  • plants can't grow.

  • And this zone goes from 200 to 1000 meters below the ocean's surface.

  • A thousand meters is taller than the tallest building in the whole world!

  • Now, Ned, can you give our audience a few examples of what animals live in this zone?

  • Uh huh!

  • There are no plants, but animals like shrimp, hatchet fish, and swordfish live here.

  • That is so interesting!

  • It truly is!

  • Wyatt, can you name the last ocean zone for us please?

  • That would be my pleasure!

  • The last zone is called the midnight zone.

  • This layer is /so/ deep that sunlight never reaches it, so it's completely dark.

  • You'll find some very unique animals in this zone that have developed special bodies

  • to live in the dark and to survive the great pressure of the deep sea.

  • There's the anglerfish, which creates a light to lure prey to its big mouth.

  • Also, there's the blobfish, which looks blobby to us, but in the deep sea, the pressure

  • squeezes it to make it look more like a fish that we would recognize.

  • And there's also massive sea creatures, like our friend The Giant Squidstravaganza!

  • That's amazing!

  • I love learning about animals, and how animals survive in different environments.

  • Indeed!

  • There are many animals in the sea, and they've all adapted to the amount of light that's

  • available to them.

  • Thank you so much Dr. Irene, Ned and Wyatt!

  • I had a great time learning about the ocean zones, and the creatures that live in them!

  • Dr. Irene, Ned, Wyatt: Thanks Jessi!

  • Did you have a good time learning with our ocean experts?

  • Do you have any questions for Dr. Irene and her assistants?

  • Let us know!

  • Grab a grown up and leave a comment down below, or send us an e-mail to kids@thescishow.com.

  • And we'll see you next time here at the fort!
