Cave Spider



Cave Spiders are neutral mobs that are currently not in Minecraft Pocket Edition, but may be added in a future update. They were speculated to be added in 0.9.0 along with abandoned mineshafts. While the latter was added, cave spiders were not due to the lack of potion effects. They will spawn exclusively in abandoned mineshafts or can be spawned by using spawn eggs in creative mode. When killed, they will drop string like normal spiders.

Combat
Combat against cave spiders is difficult, as when they attack you, they also poison you. Also, due to abandoned mineshafts being very dark, they rarely spawn neutral. They are much smaller than regular spiders, which means they can fit inside half blocks (slabs). They can be defeated easily by using an iron sword, though stone may work as well. Players should carry milk buckets as well to cure their poison.

Trivia

 * Creating cave spider farms are extremely difficult, due to the fact they can climb, their poison poses a threat to the player, they move faster, and fit in very small spaces.
 * Cave spider poison can be cured with a bucket of milk, as with other effects.
