Summary

The ways animals make sounds may surprise you! Unlike humans, vocalizations aren’t always localized in the mouth. These may emit from muscles inside their bodies. Different sounds have different purposes too, and upon observing you may find there are many sounds you weren’t aware of before.

David Mann, PhD earned his doctorate from the Woods Hole Oceanographic Institution by studying domino damselfish sounds at a Pacific atoll, and he was a faculty member at the University of South Florida. More recently, he is the Founder of Loggerhead Instruments which developed Haikubox, a tool that measures bioacoustics – the sounds that animals make to communicate. This consumer product is designed to automatically identify birds using their sounds. These boxes collect millions of birdsong recordings stored in a massive community science database which will be used for scientific discovery.

I am back with David Mann. We're talking bioacoustics and today we are specifically talking about what are the different types of animals that make

0:20.1

sounds and how do they actually do it because I think a lot of us have obviously heard

0:25.0

apples making sounds, but it might be a little bit wider

0:28.0

than I realized.

0:29.0

Like last time you mentioned, I think it was the grouper

0:32.0

that makes a sound that I just honestly don't think about fish really making sound unless it's like splashing.

0:37.2

So I'd love to hear more about that. So there's a lot of fish that make sound not all all of them, but a lot of them do.

0:43.2

And so the red grouper, you know, so it's making the sound that's like

0:48.0

boom, boom, boom, and you can listen to it.

0:50.0

It's, what it's got is a swim bladder inside.

0:54.1

So it's an air-filled bladder that most fish are using to regulate buoyancy.

1:00.2

So basically, you know, fish don't want to always sink to the bottom have to keep swimming to stay up so they basically like a diver with a buoyancy compensation best they make themselves pretty neutrally buoyant

1:12.0

But a whole bunch of fish have evolved muscles that attach to the swim

1:16.2

bladder and will drum it.

1:21.2

So, yeah. Wow, that's super fascinating.

1:25.0

So they've taken something that all the fish have and they've modified it by adding a muscle to it.

1:32.0

Yes, totally.

1:33.4

Yeah, wow.

1:34.4

That's such interesting evolution pathway.

1:37.6

Yeah, it's like, right.

1:39.1

You work with what you got, and so, right?

1:41.8

So you figure it out. Yeah, and then the one underwater creature that I think most people can think of is probably the dolphin
