Cave Spider

The cave spider is a neutral mob that can inflict poisoning.

Monster spawners
Cave spiders spawn from monster spawners in abandoned mine shafts.

Drops
They drop 0-2 string. They also have a $1/3$ chance to drop a spider eye if killed by a player. They drop 5 experience when killed by a player or tamed wolf.

Behavior
Cave spiders inherit most of their behavior from regular spiders:
 * They are pacified (made neutral) by bright light (daylight or light levels of 9 or higher). Likewise, subjecting them to darkness will render them hostile.
 * They can climb walls when needed.
 * They attack by leaping at the player.
 * They are not affected by cobwebs or poison.

However, cave spiders will not spawn with beneficial status effects and cannot spawn as spider jockeys.

Venom
When bitten by a cave spider, the bitten entity is inflicted with for 7 seconds on normal difficulty and 15 seconds on hard.

Trivia

 * The cave spider's texture appears to be at a higher-resolution than its normal counterpart - this is because the textures occupy a smaller space.
 * Despite being smaller, they have the same size shadow as a normal spider.
 * If cave spiders are allowed to spawn naturally via hacks, they will only spawn if the light level is 7 or below (like most other hostile mobs).
