A Dolphin Chasing a Raw Cod

A mob is an AI-driven game entity that resembles a living creature. Mob is an abbreviation for mobile entity. All mobs have the ability to be attacked and injured (e.g., by players or other mobs, falling into void, being hit by an arrow, etc.) and can also have some form of voluntary movement. Different mob types often have different AI and loot.

Mobs can spawn in many ways. Most mobs will spawn naturally depending on their environment, biome and light levels. Most animals can be found in bright areas, while hostile creatures are often found in the darkness (whether it's in a cave, dungeon or mansion) Animals spawn from chunk generation. However, hostile monsters spawn and despawn at specific radii around the player. Some mobs, including neutral and passive animals, have the ability to be bred and produce offspring. Villagers can also breed randomly depending upon the time of day, the number of beds, and other factors. However, they cannot be directly bred by players. Most mobs won't spawn on transparent blocks or in water (except for fish, turtles and other aquatic creatures), inlava (excepting for striders), in bedrock, or blocks less than one block tall (such slabs placed on their bottom half). Monster spawners are an exception. They can spawn monsters on any block, even air.

Some mobs, such as the snow golem or the wither, require that players "construct" them before they can spawn. The iron golem is a mob that can be spawned naturally, but can also be built. Four end crystals can be used to respawn the ender dragon.

Players can also easily spawn mobs by using spawn eggs in Creative mode or the /summon command.


Mobs are just as affected by the environment as the player. They are subject to the same physics and can be injured by the same things as the player (catching on fire or falling, drowning, being attacked by weapons, etc.). Some mobs are more resistant than others to certain hazards, like some Nether mobs that are immune to fire. All aquatic mobs, except dolphins, are immune to drowning. Mobs have the ability to ride minecarts, and can climb ladders. Mobs that are killed turn to dust and may drop useful resources. Each mob type in Minecraft has an AI (artificial Intelligence) system that has different behavior and mechanics. Mobs will wander around randomly if there is a player nearby. They also avoid falling damage by not stepping on blocks high enough. Many mobs have advanced path-finding systems that allow them to navigate through obstacles to reach their desired destination or object. Passive mobs will run in random directions after being injured, while hostile mobs will chase or attack the player whenever they get close. Neutral mobs are neutral until a player/mob provokes them (usually by attacking), then the neutral mob becomes hostile towards the entity that it has hit. While most mobs can see players within 16 blocks, some mobs can see further. Players can hear most mobs from 16 blocks away (spherical). Mobs in creative mode can be harmless.

Most mobs can't see through solid blocks, even semi-transparent blocks like glass, glass, tall grass, and ice. Mobs will not attempt to walk on rail tracks, unless they are pushed onto them by other mobs.

These mobs either

- They were not to be added in a future version (the mobs which lost the MINECON Earth 2017 vote) - Were believed to have a chance of being added in a later update (the mobs who lost the Minecraft Live 2020, Minecraft Live 2021 mob votes and the Firefly).
- Not known to be under consideration for future updates (the Red Dragon or the mobs that lost in the China Edition mob vote).

Mobs of undead

This group of mobs includes drowned husks and phantoms as well as skeletons and skeleton horses, withers, wither skulls, withers, wither bones, zoglins and zombies. These mobs can be damaged by potions for healing, or healed by potions for harming. They are immune to poison damage and drowning (except zombies and husks, who turn into zombies and drown if drowning respectively). If they touch water or wear a helmet, zombies, strays and phantoms will burn in direct sunlight. The fire resistance effect allows undead mobs to catch fire in direct sunlight, but not be hurt by the fire. Except for drowned, withers, and phantoms all undead mobs sink in water. All undead mobs take additional damage from weapons enchanted in Smite and are ignored or ignored by withers.

Most undead mobs can pick up items. Some can spawn in armor or holding weapons or tools.

Mobs of aquatic animals

This group of mobs include axolotls and dolphins, squids. They are susceptible to being enchanted by Impaling tridents [Java Edition only][until JE Combat Tests]. They also take additional damage from pufferfish that inflate or take damage from them. All aquatic mobs, except dolphins, are immune to drowning. Turtles, guardians, elder guardians and turtles, however, take suffocation damages if they are out of water for too much. Aquatic mobs can swim, while other mobs float on water or sink. These mobs are not classified in Bedrock Edition.


This group is made up of mobs that are based on arthropods such as spiders, cave spiders and endermites. When attacked with weapons enchanted by Bane of Arthropods, they take additional damage and get the Slowness IV effect.


This group includes pillagers, illusioners[JE][unused mob], and ravagers[BE]], as well as vindicators and evokers. They are immune from evoker fangs damage, and they are ignored by vindicators named Johnny (except ravagers[Java Edition]). They are hostile to villagers, wandering traders and iron golems, as well as players in Survival or Adventure mode. In raids, they may be accompanied by vexes and witches. Illusioners (and witches[Bedrock Edition]) can see targets or players through blocks.
