How Do River Insects Breathe Underwater?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How do river insects breathe underwater?

The Big Idea

Many young river insects breathe underwater with gills, thin feathery parts that pull oxygen out of the water! Different insects wear their gills in different places. Clean, fast, cool water gives them the most oxygen.

Feathery Gills

Step one: gills. Gills are thin, feathery parts with lots of surface, so they can soak up the oxygen that is dissolved in water. Fish have gills, and so do many young insects, like tiny underwater lungs on the outside.

Gill Spots

Step two: where are they? A mayfly nymph has gills along the sides of its body, which flutter like tiny leaves. A stonefly nymph has gills near its legs, and it lives hidden under rocks in fast, cool streams.

Stonefly Push-ups

Step three: push-ups! A stonefly nymph does push-ups on the river bottom. Bobbing up and down moves fresh water over its gills, bringing in more oxygen when the water is still.

A Closer Look

Let's take a closer look! A nymph is a young insect that lives underwater. Its gills catch oxygen from the water. Push-ups stir the water around those gills. Clean, cool, fast water has the most oxygen.

Quick Facts

Quick facts! Stonefly nymphs really do push-ups. Mayfly gills flutter along the sides. Cold, fast water holds lots of oxygen. Stay with a grown-up near any river.

Think Like a Scientist

Now, think like a detective! Do ten push-ups yourself and notice how your breathing changes. Then draw a stonefly doing push-ups on a river rock. Show it to someone you love! Share what you discover with a grown-up.

Outro

River insects breathe through gills, and sometimes do push-ups to help. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
