Yes, spiders get caught in the webs of other spiders frequently. And it isn't usually a pleasant experience for them.
Theoretically, they might well be able to navigate another spider's web skilfully, but they are rarely given the choice. Spiders attack other spiders and if anything, spiders from the same species are more likely to attack each other than spiders of other species.
Most commonly, a spider will grasp and bite its intended victim and inject venom. Karen Yoder of the Entomological Society of America explain, "Paralysis from the bite causes them to be unable to defend themselves and eventually they succumb to or become a meal!"
The main enemies of spiders are spiders themselves. But not all spiders attack their own. There are about 20 species of social spiders that live together peacefully in colonies.
