Chambered Nautilus
The chambered nautilus is a creature that lives in the ocean. It has a very special shell that it lives inside. The shell is kind of like a house for the nautilus.
The shell is made up of lots of different chambers that are all connected together by something called a siphuncle. Imagine a number of rooms in a house, with doors connecting them. It's like that!
When the nautilus wants to move, it uses something called jet propulsion. This means it shoots water out of its body to move forward. It's kind of like a rocket that shoots flames to go up. But the nautilus can only move so quickly because it has a heavy shell it has to carry around.
The chambered nautilus is really special because it is one of the only creatures left that has a shell like this. It has been around for millions and millions of years, so it's one of the oldest animals still alive today!
