A nautilus shell is an item that is used for crafting conduits.

Fishing
Nautilus shells can be rarely obtained as a treasure item from fishing. The drop chances of nautilus shells increase with each level of Luck of the Sea on the player's fishing rod.

Drowned
3% or 8% of drowned spawn with a nautilus shell in the offhand, and this nautilus shell always drops upon death.

Trading
Wandering traders may sell a nautilus shell for 5 emeralds each.

Trivia

 * Nautiluses are animals that occupy deep oceans in the real world. However, they are absent in Minecraft and there are currently no plans to add nautilus mobs into the game.
