The cave spider is a neutral mob that can inflict poisoning.
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) but will continue attacking regardless of light change once hostile. Subjecting them to darkness will render them hostile.
- They can climb walls when needed.
- They attack by leaping at the player.
- They are unaffected by cobwebs or poison.
- Can fit through a space that is 1 block wide and half a block tall.
- Runs much faster than spiders[Pocket edition only].
- Poison damage does not work when the player has 1 health left.
- Can go through the spaces between Nether Brick and Normal Fences.
Unlike regular spiders, they do not spawn with status effects.

Issues relating to “Cave Spider” are maintained on the issue tracker. Report issues there.
- 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).
