The Mounts of Mayhem update adds one of the most unique underwater companions Minecraft has ever seen—the Nautilus. Unlike most aquatic mobs, this creature isn’t just something you swim past. It can be tamed, saddled, ridden, armored, bred, and even used for long underwater expeditions without worrying about your oxygen bar.
Where Nautilus Spawn
Nautilus mobs generate in all ocean biomes, which makes them widely accessible once you know where to look. You won’t find them near the surface—these mobs appear below Y-level 38, often in small groups of two or three. That means spotting one usually means more are nearby.
Because of the depth, it’s smart to prepare Water Breathing potions or bring gear that helps you stay submerged longer. Constant resurfacing can cause you to lose track of them, especially since they don’t stay in one place for long.
What You Need to Tame a Nautilus
Taming a Nautilus requires pufferfish—either the raw item or a pufferfish-in-a-bucket.
- Both Java and Bedrock editions accept either type of pufferfish for taming.
- On Bedrock Edition, pufferfish cannot be fished in jungle-related biomes, so move to other waters if needed.
- The Nautilus rarely accepts just one fish, so bring several.
Since pufferfish are also used in crafting Water Breathing potions, it’s worth collecting a handful before you start the hunt.
How to Tame a Nautilus
Once you spot a Nautilus, the taming process is simple but may take a few attempts.
Here’s the full step-by-step method:
- Approach calmly. Sudden movements won’t scare it off, but staying close without drifting is helpful.
- Hold a pufferfish in your hand.
- Interact with the Nautilus to feed it.
- Repeat until you see heart particles, which confirm the creature is now tamed.
- The Nautilus will become passive toward you and ready for riding once equipped.
Just like wolves or cats, taming is random—sometimes you’ll get lucky with one pufferfish, sometimes it’ll take several.
How to Ride a Nautilus
A tamed Nautilus becomes a fully functional underwater mount when given a saddle.
How to equip and ride it:
- Hold a saddle and interact with your tamed Nautilus to place it.
- Interact again to mount it.
- Move using normal directional controls.
- Use the jump key to charge its dash, releasing for a powerful burst of speed.
While riding, you gain the Breath of the Nautilus effect, which temporarily pauses the oxygen meter, letting you travel underwater far longer than swimming. This makes the Nautilus an excellent partner for monument raids, deep-ocean exploration, and underwater structure searches.
If you want extra defense, the mob can wear Nautilus Armor, which appears in treasure loot such as shipwreck or ocean ruin chests.
Nautilus Behavior and Abilities
A few important traits make the Nautilus stand out:
- It propels itself forward using a jet-like motion.
- It cannot survive on land—it will suffocate quickly.
- When provoked, it can perform a dash attack that deals damage.
- When ridden, its dash can also serve as a mobility tool or attack burst.
- It is neutral when wild but becomes fully passive once tamed.
There is also a hostile cousin, the Zombie Nautilus, sometimes ridden by Drowned. These must be defeated before taming the creature beneath them.
How to Breed Nautilus
Breeding Nautilus helps create a long-term underwater stable.
Breeding steps:
- Bring two Nautilus together.
- Feed each of them any type of fish or bucketed fish.
- They enter love mode, producing a baby Nautilus.
- Juveniles eat up to 10 fish before growing into adults—and if you feed it from birth, the baby becomes automatically tamed.
Fish also serve as healing food for injured Nautilus.
Tips for Keeping Your Nautilus Safe
Since the Nautilus cannot leave the water, consider:
- Building a dock or underwater stable near your base.
- Using leads (they work underwater) to prevent drifting.
- Keeping them away from Drowned and Zombie Nautilus groups.
- Equipping armor whenever possible.
If a saddled or armored Nautilus dies, it drops the equipped items, but the mob itself yields only minimal XP—far better to protect and keep them alive. Play Now!
