Chambered Nautilus

This mullosk, called the chambered nautilus, eats plankton. As it grows, the nautilus grows more chambers. This is an example of a living fossil. I became interested in learning about the chambered nautilus when my grandpa showed me a huge cephalopod fossil at my house. This also helped me learn about how fossils are formed. I have actually seen a live chambered nautilus at the Dallas Aquarium. It was cool!
