Nautilus

Nautilus refers to a marine creature known for its distinctive shell, which is often used as a symbol of natural beauty and mathematical elegance. Belonging to the family of cephalopods, which includes squid and octopuses, the nautilus has a coiled, chambered shell that helps it with buoyancy in deep ocean waters. Each chamber can be filled with gas or fluid, allowing the nautilus to control its depth. This ancient species has existed for millions of years, providing insight into marine evolution and biodiversity. The nautilus is often admired for both its unique shape and its ecological significance.
