Nautilus

About

How nautilus lives

Nautiluses are shelled cephalopods that rise and sink along deep reef slopes to scavenge and hunt. A nautilus controls buoyancy with gas-filled chambers inside its shell. Ocean animals navigate three-dimensional space, pressure, and constantly shifting currents.

Conservation

Status and habitat pressure

Vulnerable species face mounting risks and can decline quickly if habitats continue to shrink. Protecting nautilus also depends on keeping ocean, coral reef habitats healthy and connected.

Vulnerable species can decline quickly when habitat loss, climate pressure, or human conflict intensifies.

Quick Facts

Things to notice

• A nautilus controls buoyancy with gas-filled chambers inside its shell.
• Many fish detect subtle vibrations in the water, helping them react quickly to motion nearby.
• Ocean animals navigate three-dimensional space, pressure, and constantly shifting currents.
• Vulnerable species face mounting risks and can decline quickly if habitats continue to shrink.
