Coccolithophore

Okay, kiddo, let me tell you about something called a coccolithophore. It's a tiny living thing that lives in the ocean. Imagine a very, very small plant that is actually a single cell, just like you have cells in your body, but way smaller than you can see even with a microscope.

What's special about coccolithophores is that they create armor for themselves out of something called calcium carbonate. It's like they are building a tiny suit of armor to protect themselves from predators in the water.

But that's not all. They also create these cool things called coccoliths. These are small, flat, circular plates made of the same calcium carbonate. If you looked at them really close, you would see a lot of tiny, intricate designs that the coccolithophore makes. Scientists can study these designs to learn more about the history of the ocean and climate change.

So basically, coccolithophores are tiny ocean plants that make armor for themselves out of calcium carbonate and also create little plates called coccoliths, which scientists can use to learn more about the ocean and climate over time.
