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.
 * Because Bedrock allows for Nautilus shells to be held in the off-hand, they are the only item in that version that can be put in the off-hand slot without having a specific function.
 * This is likely to make it possible for Drowned to occasionally spawn with the item in their off-hand.
 * This feature makes it possible for to occur without commands (they will use player animations instead of zombie animations).
