Information About Other Types of Spiders
About 35,000 spider species have been identified throughout the world and about 3,000 in the United States. These arachnids have eight legs and two body segments. Spiders have three or four pair of eyes but are not thought to see well and do not use sight for hunting prey.
Spiders do not have chewing mouthparts and commonly utilize digestive enzymes in their saliva to break prey down before consuming it. Additionally, the gut of a spider is too narrow to allow for consumption of large food particles. Almost all spider species are predators, although one vegetarian species has been documented.
Spiders are capable of producing silk that is elastic, adhesive and strong. This silk is used to spin webs as well as to construct egg sacs and line spider dwellings. The size and shape of spider webs vary by species: some are orb-shaped, while others are funnel-shaped; some webs are orderly, while others appear haphazard. Some spider species live in burrows rather than webs.
