Hi, I'm Lindsay.

And I'm Marshall. Welcome to Tumble, the show where we explore stories of science discovery.

Today we're asking, what sounds do fish make?

So is this one of those like the cow goes moo, the fish goes fish?

Fisch.

Exactly.

We know that animals use all kinds of interesting sounds to communicate, but how do fish do it underwater?

We're going to find out how scientists are tuning in to what fish have to say.

Tumble listener Josie thinks she has the answer to what fish sound like.

Hi, my name is Josie, and I'm seven years old, and I think these fish would sound like.

Blub, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah. Okay, blub, blub, blub, blub, blub, blub, blub, blub, blub.

Okay, Josie, I mean, I think they would be saying one fish, two fish, redfish, bluefish. But I guess to those of us who are just hearing them in the water, it would probably just sound like blub, blub, because, you know, they're underwater. Okay, well, let's put Blub, Blub, Blub as the hypothesis or idea of what the

answer might be. But how would scientists find out? Josie has an idea. I think scientists could find out

by looking at their DNA while they talk. Oh, I mean, I guess fish DNA might hold the secrets to make fish talk.

So let's ask our listeners.

First, what sounds do you think fish make?

And how would scientists find out?

Think about it because we're about to splash into the world of fish sounds with a scientist who has made it her goal to collect all the fish sounds in the world.

To find out what fish sound like, I talked to Audrey Luby, an ecologist who studies the

interactions between fish and their environment. And I asked her why she's so focused on fish sounds.

Fish sound very funny, as I'm sure we'll hear on this podcast. Wait, fish sound funny, and that's why she's studying them?

For Audrey, fish sounds are not only hilarious.
