Skeleton

The skeleton is a hostile mob that was introduced to the game in Survival Test and remained in all later versions of the game. Skeletons are fairly fast-paced enemies that will shoot arrows at the player at a decent speed, making them very dangerous enemies. Like Zombies, skeletons only spawn in dark areas, such as unlit areas on the surface at night, or in unlit caves. If the sun is at a 15 degree angle or greater on land, they will be lit on fire and take burn damage until death.

Skeletons can hit other mobs with their arrows. If they hit another hostile mob it will cause both of them to ignore the player and start fighting each other until one of them dies.

Skeletons also have a 1% chance to spawn mounted on spiders. Since the Halloween Update, skeletons now hold a bow in their hands.

History
In Survival Test, Skeletons are spawned randomly in new Survival maps and follow players when approached, much like Zombies. They appear to fire arrows at a faster and more random rate and upon death, will shoot out 5-6 arrows around themselves. Arrows fired by skeletons at that time could be picked up and used by players. They take 5 hits to kill and can wear NPC armour, although the armour does not give them any additional hit points.

Trivia

 * Skeletons have the same face as zombies, but with a mouth and a different colour.
 * If a skeleton kills a creeper, the creeper will drop a record.
 * Skeletons legs have the same texture as their arms.
 * In beta, if you are under the skeleton, it will shoot itself.
 * Though they have the same pose as a zombie, they will not deal any damage from touching you like zombies do. However, being that they fire their bows even at point blank range, there is little difference.
 * Skeletons fire arrows immediately when the player is in shooting range, making it hard to sneak up on it.
 * Skeletons will attack Spiders and Zombies if they are attacked by such creatures.
 * If one skeleton hits another skeleton with an arrow (usually by firing at the player and missing), both skeletons will ignore the player and begin firing at each ither, slowly moving in a circle. As soon as one skeleton is killed, the other will begin to attack the player if it is in range.
