Mobs are the animate moving entities in Minecraft, also known as monsters or mobiles. Generally, mobs are affected by the environment in the same ways as the player—they are subject to physics, the elements (burning and drowning), gravity, suffocating, motion, and increase and decrease of speed, health, and movement. When mobs are killed, they drop items which may be useful resources. Mobs have a sight range of 16 blocks, excluding Ghasts, which have a sight range of 100 blocks, and Endermen, who have a sight range of 64 blocks.
There are currently 31 active mobs, excluding the player.
