DESCRIPTION

The Chambered Nautilus (Nautilus pompilius), also known as the Pearly Nautilus, is a cephalopod characterized by its distinctive, spiraled, chambered shell with brown and white patterns. Often referred to as a 'living fossil,' it has remained largely unchanged for millions of years. It uses jet propulsion for movement and adjusts its buoyancy by regulating gas and fluid in its shell chambers. They are nocturnal scavengers, primarily feeding on crustaceans, small fish, and carrion using around 90 suckerless tentacles and a keen sense of smell.
