Usable items

A nautilus is a neutral mob that can be tamed, saddled, and ridden as an underwater mount that can dash and protects the rider from drowning. With no rider, it uses its dash to hunt pufferfish and to briefly retaliate if attacked. It can also be equipped with nautilus armor.

Spawning

[edit | edit source]

Nautiluses spawn in all ocean biomes, in groups of 1-3. Nautiluses spawn between levels 38 and 58.

In Bedrock Edition, nautiluses have a 10% chance to spawn as a baby.

Nautiluses count towards the "water creature" mob cap and can despawn like other such mobs until the first time any player interacts with it, which at that point it becomes persistent and no longer counts towards any mob cap.

Behavior

[edit | edit source]

Like its real-world namesake, a nautilus's mouth and tentacles face backward with respect to their movement direction. Being an aquatic mob, they are affected by the Impaling enchantment in Java Edition.

Nautiluses follow players holding any fish or bucket of fish within a 10-block radius.

Nautiluses are immune to the Poison effect.

Tamed nautiluses randomly swim around up to 32 blocks away, or 16 blocks if saddled.[verify][more information needed]

Attacking

[edit | edit source]

Nautiluses occasionally dash toward and attack nearby pufferfish. They also retaliate against players and mobs if provoked, using their dash attack. When dashing toward a target on land, nautiluses can launch themselves out of the water and accidentally become beached on land, where they are unable to move.

They may also unintentionally attack a mob or player that stands between them and their target.

When they are hostile, nautiluses cannot be leashed.

Taming

[edit | edit source]

Nautiluses can be tamed by being fed pufferfish or buckets of pufferfish. Each pufferfish or bucket of pufferfish has a 13 chance of taming the nautilus.

Healing and breeding

[edit | edit source]

Adult nautiluses can be healed (or bred if at full health) by being fed any fish or any bucket of fish.

Baby nautiluses require 20 minutes (24000 game ticks) to grow up into adult nautiluses. This process can be sped up using any fish or any bucket of fish:

  • in Bedrock Edition, it takes 10 fish or bucket of fish for a baby nautilus to become an adult;
  • in Java Edition, each fish or bucket of fish fed to a baby nautilus reduces its remaining growth time by 10%.

Weaknesses

[edit | edit source]

Nautiluses take suffocation damage on land, like most other aquatic mobs. Similarly to squid, nautiluses on land remain stationary rather than flopping around like fish. They can be controlled and even dash when on land, with their movement being much slower.

Usage

[edit | edit source]
A nautilus being ridden by Steve
See also: Transportation

Tamed and saddled nautiluses can be used as a means of underwater transportation. When ridden, the player is granted the Breath of the Nautilus effect, which pauses the oxygen bar while underwater, making it so resurfacing for air is no longer needed. The effect is ambient, meaning that the effect on the HUD has a blue outline, similar to effects from beacons.

Equipment

[edit | edit source]

Tamed adult nautiluses have two equipment slots:

Baby nautiluses cannot be equipped, as they cannot be ridden.

Equipment can be placed on a nautilus by holding it and then pressing the use control on the nautilus, or by accessing the nautilus's inventory. This can be done by pressing the use control on the nautilus while sneaking, or by mounting the nautilus and pressing the inventory control. A dispenser can also place a saddle or nautilus armor if it is facing a tamed nautilus.

The equipment can be removed by two methods:

  • Removing the equipment from their slots in the nautilus's inventory.
  • Using shears on the nautilus. If both a saddle and nautilus armor are equipped, they are removed one at a time. The first use removes the nautilus armor, and a second use removes the saddle.

Riding

[edit | edit source]
Main article: Riding

Once a nautilus is tamed and saddled, the player can control it with the standard directional controls; pressing forward moves the nautilus in the direction the player is facing. The player dismounts using the dismount control. In Bedrock Edition, it is impossible for a player to use a Nether portal or End portal while on a nautilus.

A nautilus gradually gains speed while moving in a straight line, up to a swimming speed of 6.5 m/s. A nautilus can still move on land when controlled by a player, but is significantly slower, moving at a maximum of 0.88 m/s.

Saddled nautiluses also have the ability to dash. When the player rides them, the experience bar on the HUD is replaced by a dash charging bar. Dashing is done using the jump control: holding the control charges for a longer dash. When dashing, a nautilus launches up to about 12 blocks forward. A nautilus can dash every 2 seconds. Dashing while moving upward near the surface results in a quick breach, wherein the nautilus and its rider break the surface briefly.
