The Ancient Nautilus
Living Fossils
Nautiluses are ancient marine mollusks, often referred to as living fossils. These cephalopods have remained largely unchanged for millions of years. Their coiled, chambered shells can reach up to 10 inches in diameter, providing buoyancy and protection. Their unique appearance and ancient lineage make them fascinating subjects of marine biology.
Deep-Sea Survivors
Nautiluses inhabit the deep slopes of coral reefs in the Indo-Pacific region. They rise to shallower waters at night to feed on small fish and crustaceans. Their unique buoyancy control system, using gas-filled chambers, allows them to navigate the depths with ease, showcasing a remarkable adaptation to their deep-sea environment.
