Spider

The spider was the second mob added to the game. The spiders' eyes glow red and can be seen in the dark, making their appearance rather creepy. Unlike most other hostile mobs (1x1x2 box), the spider is a flat mob (2x2x1 box). It cannot enter the same narrow spaces that zombies and other tall mobs can, but it can crawl into places where the ceiling is too low for any other mobs. Seeing as they are much larger than zombies, they can be hit rather easily with arrows. A lone spider is easy enough to deal with, but a pack can quickly close distance on the player due to their jumping ability-in which they can jump 2-3 blocks.

During the day, Spiders become passive, and will not become aggressive unless they are attacked. When spiders are in a passive condition, their eyes do not glow red. The player will not receive damage if they touch them. Spiders become aggressive again as soon as night falls or if the player moves into darkness. If they were chasing the player during the night, they will usually continue to chase them during daylight.

Spiders make a sound like someone slurping a straw or a mix of a screech and paper rustling and their distinctive noises can warn the player of their presence.

Spiders can spawn mounted by skeletons.

Hunting
Spiders can prove difficult to hunt, but because they drop string, they can be a very rewarding kill. Proper equipment for hunting spiders includes a weapon, like a sword or bow, and some type of armor. However, due to their great ability to close distances, bows are preferred by many players as spiders present a large target. When attacking a group of spiders it is recommended to pick off the ones that aren't too close to others in order to avoid startling them all at once. Spiders are one of the most aggressive mobs in Minecraft, and should never be underestimated.

History
Spiders were first introduced to the game in Survival Test and haven't changed much. In Survival Test, they moved at the same speed as in Beta, but they could not jump as far. Killing this mob netted you 105 points. Spiders were once brown.
