From the brains behind brains on this is the moment of um. Moment ofum comes to you from APM Studios.

I'm Sigourney Beaver. Ugh. Another serene day by the lake. As a famous Beaver actor, it's important to take time away from the hustle and bustle of Hollywood. It took me years to learn this. Why, I

remember when I was just a fresh-faced young Beaver playing a New York City

musician whose apartment becomes a hub of

By the time we finished filming I was exhausted I could barely gnaw on a piece of

wood let alone prepare myself from my next role I said to myself,

so Gorney, you must find a place of your own

where you can unwind.

The rest is history. I found this incredible lakeside paradise, the most beautiful

little corner of the world and... Oh, did you just hear that? It sounded like...

Well, great. The fish are hurling themselves out of the water again.

Have you ever seen this before? A fish suddenly flings itself up out of the water like a silver torpedo and lands with a giant splash.

It's quite disruptive to my rest and relaxation.

Why do they do that anyway?

My human fans, Paige and Max,

were wondering the same thing. So the short answer to why fish jump out of the water

is that there's either something in the water that they want to get away from,

so a predator or poor water quality, or there's

something outside of the water that they want to get to.

My name's Dr. Keegan Lutek and I'm an aquatic biologist. So for example some fish will jump out of the water to actually catch food or to lay eggs or to go and find other bodies of water.

Lots of fish will jump if, for example, there's not a lot of oxygen in the water
