Nautilus

The nautilus is a marine cephalopod mollusk, the sole surviving genus of the family Nautilidae. Characterized by its distinctive, chambered spiral shell, the nautilus inhabits the deep waters of the Indo-Pacific. These ancient creatures, often referred to as 'living fossils', have remained largely unchanged for millions of years. They navigate the ocean using jet propulsion, and their tentacles are used for capturing prey. The nautilus's shell also acts as a buoyancy control system, enabling vertical movement in the water column. They are a beautiful creature and a reminder of a bygone era, and are extremely unique in appearance.

Nautilus meaning with examples
