Deep Sea Landscape with a Nautilus Shell
The ocean landscape features a nautilus shell with its distinct spiral form alongside a sea urchin shell. Coral formations grow along an underwater cliff, surrounded by natural ocean seaweed growing in the marine environment.
Fascinating Facts About the Nautilus
Nautiluses have existed in the oceans for hundreds of millions of years, earning them the nickname of living fossils. They use gas-filled chambers inside their spiraled shells to adjust their buoyancy and float through deep waters. Unlike most other mollusks, a nautilus can have up to ninety small tentacles to help it navigate and capture food.
