Evolved Spider

Evolved Spiders on the Moon

Evolved Spider can be, depending on light level, a passive or a hostile mob that the spawns on the Moon and Mars. They are slightly bigger than their Overworld counterparts. They appear to be wearing two medium oxygen tanks, and oxygen gear and helmet.

Likely most of Minecraft hostile mobs, they will spawn in dimly lit areas except on Space Station and vanilla dimensions.

Evolved Spider Jockey

There is a rare chance of spawning a spider jockey, but in this case it will spawn with a vanilla Skeleton riding the Evolved Spider. The jockey mob is doomed to die of suffocation in less than 1 minute.
