There's the ones that are dolphin-like that have really high-pitched vocalizations that use echolocation.

And there's the ones that are big and humpback-like.

And they have really low voices.

And scientists typically think of them as not using echolocation.

I have to believe that they must be right.

But when I listen to Humpback Whale songs,

I feel like it has to be doing some echolocation functions.

So like low sound travels much better in water than in the air, five times faster and farther.

And then the sounds of whales can travel like halfway.

I mean, it's like 5,000 miles.

It might be halfway around the world.

So they, you know, the way humpbacks do stuff is at the summer, they go to the poles and

And they go eat.

At winter, they come to the equator and they mate.

And that's where the singing happens.

But the singing starts happening before that.

And presumably it can be heard at the poles.

And so it's like an attractive beacon.

And there's like these different places.

So I like to think of these like music festivals.
