CHAMBERED NAUTILUS Meaning and
Definition
-
The chambered nautilus is a marine cephalopod mollusk belonging to the family Nautilidae, characterized by its distinct spiral-shaped shell divided into numerous enclosed compartments or chambers. This unique shell structure is composed of a series of gas-filled chambers, each larger than the previous one, connected by a narrow tube, called a siphuncle, which allows the nautilus to control its buoyancy. The shell itself is typically pale, displaying a beautiful natural pattern of concentric ridges and stripes, ranging in color from whitish to brownish.
The nautilus is known for its primitive appearance, resembling ancient shelled cephalopods that thrived over 500 million years ago. It is often referred to as a "living fossil" due to the persistence of its form over time. While its distant relatives, such as ammonites, became extinct, the chambered nautilus has survived and can be found in the warm tropical waters of the Pacific Ocean, primarily around the coasts of Australia, the Philippines, and Indonesia.
The chambered nautilus is an intriguing creature that resides near the ocean floor and feeds on a diet consisting mainly of small fish, shrimp, and other crustaceans. It has a soft body with tentacles, and its eyes are well-developed, providing it with good vision. These ancient creatures move through the water by using jet propulsion, expelling water out of its excurrent siphuncle to swim in different directions.
Due to their mesmerizing aesthetics and biological significance, chambered nautiluses are highly sought after by collectors of shells and nature enthusiasts. However, their populations are declining due to overfishing and habitat destruction, causing concerns among conservationists who strive to protect their existence and ensure the continued survival of this remarkable species.

Etymology of CHAMBERED NAUTILUS
The word "chambered nautilus" is derived from two separate sources:
1. Chambered: The term "chambered" refers to the unique structure of the nautilus shell. The word itself comes from the Old French word "chambre", meaning "room" or "chamber". This is because the shell of the nautilus is divided into a series of progressively larger and interconnected chambers. Each chamber is formed as the nautilus grows, with the animal residing in the newest and largest chamber.
2. Nautilus: The word "nautilus" has its origins in ancient Greek. It is derived from the Greek word "nautilos", which means "sailor" or "sailor of a ship". This term was used to describe the creature because the underside of the nautilus shell resembles a sail.
