Chambered Nautilus

The chambered nautilus lives in the depth of the ocean in Australia and Indonesia, but if you are in the famous Monterey Bay Aquarium in California than you are in luck because you can spot these amazing ancient creatures up-close. These alien-looking-weird-shaped aquatic animals are the oldest in the world. Fossils have been found that makes it over 500 million years old and surprisingly, they still look the same as they were reconstructed from the fossils. Are they alive?
