How does a baby turtle cut its way out of its egg?

Video · 1:48 · Crafty Clover explains, from A Million Whys Book 32

A baby turtle has a little hard bump on the tip of its snout called a caruncle, or egg tooth. It uses the bump to slit open the shell from the inside, and then it pushes its head out. After a rest, it climbs out. A few days later, the egg tooth falls off because the baby doesn’t need it anymore. It is a tool just for hatching.

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a baby turtle cut its way out of its egg?

The Big Idea

A baby turtle is sealed inside its egg. How does it get out? It has a special tool!

A Little Bump

Step one: A Little Bump. A baby turtle has a little hard bump on the tip of its snout called a caruncle, or egg tooth. It isn't a real tooth, but it's sharp enough to do the job.

Slitting Open

Step two: Slitting Open. It uses the bump to slit open the shell from the inside. Then it pushes its head out, rests, and climbs out.

Falling Off

Step three: Falling Off. A few days later, the egg tooth falls off because the baby doesn't need it anymore. It's a tool just for hatching.

A Closer Look

Let's take a closer look! On the snout. From inside. Then climb. Days later.

Quick Facts

Quick facts! Lizards and snakes have an egg tooth too. The egg tooth is called a caruncle. It cuts the shell from inside. It falls off in a few days.

Think Like a Scientist

Now, think like a scientist! Draw a baby turtle cracking out of its egg. Label the egg tooth on the tip of its snout. Add cracks to the shell. Color the baby turtle. Draw it a few days later without the egg tooth.
