You're listening to Brains on, where we're serious about being curious.

What has eight arms and is super cool?

An octopus.

Well, yes, those are certainly cool, but I was thinking of spiders.

Oh, I love spiders, but I would describe them as having eight legs.

Good point. We say octopuses have arms, but usually people say spiders have legs, but like, what's the difference?

Well, I guess it depends on what you use them for most, walking or grabbing.

Yeah, it's like hair and fur. We say animals have fur, but we have hair. But they're made of the same stuff.

Oh gosh, you're right. My brain is starting to hurt.

Yeah, me too. Or like a whale's blowhole. It's basically the same as our noses. So why don't we call that hole the whale's nose?

Or why don't we call the thing on our face a blowhole? Next time I have a cold, I'm going to say my blowhole is runny.

Great idea. I'm going to do that too. But back to my original thought.

What has eight legs? And is super cool? Spiders.

When we eat, we chew it up and swallow it and all the breakdown of that food happens inside our bodies with spiders that happens on the outside.

That's Dr. Paula Cushing. She's been studying spiders for over 30 years. We'll hear more from her in a bit.

If you like spiders or wasps or fun, I advise you stay tuned.

You know, Molly, podcast is a weird name, don't you think?

I guess I never thought about it.

When I hear the word pod, I think of a pot of whales.

And cast?
