Why do hatchlings carry a built-in lunchbox?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do hatchlings carry a built-in lunchbox?

The Big Idea

Baby reptiles hatch with a packed lunch! It's inside their bellies. What is it?

The Yolk Sac

Step one: The Yolk Sac. Before a baby reptile hatches, it has a yolk sac attached to its belly. The yolk is a store of food.

Absorbing It

Step two: Absorbing It. After hatching, the baby absorbs the leftover yolk into its body. This feeds it for days.

Time to Hunt

Step three: Time to Hunt. That gives the hatchling time to find its first meal. A yolk-sac lunchbox is a clever way to start life, and eventually it's absorbed completely.

A Closer Look

Let's take a closer look! Stored food. Its home. Absorbs it. Found later.

Quick Facts

Quick facts! The yolk sac is eventually absorbed completely. Yolk is stored food. It lasts for days. Then hatchlings hunt.

Think Like a Scientist

Now, think like a scientist! Pack a mini lunchbox with a snack for a day trip. Think about how long it would last. Think about how a baby turtle carries its own lunch. Where does it keep it? Draw both lunchboxes.
