She's a marine biologist.
That's a scientist who learns all about the living things under the sea.
Tuni loves the ocean.
Let's head to the beach and see if we can find her.
Hey, Tuni.
I knew we'd find you here.
Well, it's lucky for us, 'cause we have a question.
How do fish breathe underwater?
Yes.
It's what keeps us alive.
If you put your hands on your chest and take a deep breath in, you can feel your lungs get bigger as they fill with air.
My chest goes up and down.
Just like there's oxygen in the air, there's also oxygen in the ocean, and fish need to breathe it just like we need to breathe air.
Ah.
So do fish have lungs just like us?
It's hard to tell what happens under the sea from up here, so let's imagine ourselves as animals under the sea.
I wanna be a octopus.
Yeah, I wanna be a dolphin.
