Why Do Big Ears Help Some Desert Animals Cool Off?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do big ears help some desert animals cool off?

The Big Idea

Big ears have lots of tiny blood vessels near the surface! When warm blood flows through the thin skin, heat escapes into the air, and the blood returns cooler. Big ears work like radiators.

Blood Flows Through

Step one: blood flows through. A big ear is thin and full of tiny blood vessels near the skin. Warm blood from the body flows right through it.

Heat Escapes

Step two: heat escapes. The heat leaves through the thin skin of the ear and drifts into the cooler air. The blood then flows back into the body a little cooler.

Ears With Two Jobs

Step three: two jobs. Fennec foxes and jackrabbits use big ears like radiators. Large ears also help them hear predators and prey from far away.

A Closer Look

Let's take a closer look! The fennec fox has huge ears for its size. The jackrabbit has long ears too. Blood vessels fill the thin skin. Heat escapes into the air. Big ears keep these animals comfy, even when the desert is hot, and they also listen for danger.

Quick Facts

Quick facts! A fennec fox's ears can be about 6 inches long. That is huge for such a small fox. Jackrabbits have long ears for cooling too. Admire wild animals from far away, and never chase them.

Think Like a Scientist

Now, think like a scientist! Trace your hand on paper and cut it out as a pretend ear. With a grown-up watching, wave it in front of your face. Moving air carries away some warmth. That is a bit like a cooling fin.
