Orb Weavers are difficult to distinguish from other kinds of spiders that live in webs, especially cobweb spiders. The best way to tell the difference between orb weavers and cobweb spiders is by looking at the web itself: the webs made by orb-weavers are very organized, and resemble a circular grid. The webs of cobweb spiders appear disorganized and messy. Orb weavers have 8 eyes, and they usually have large spherical abdomens.
