Invertebrates Around Las Vegas, Wildlife Around Las Vegas

General: Spiders are a diverse group of hugely abundant animals in the desert around Las Vegas. Spiders are recognized from other invertebrates by their eight legs, two body segments, and spinnerets (which produce the silken material they use to spin webs). Spiders do not have wings or antennae. Most spiders are small and harmless, others are big and harmless, and a few are medium and harmful. |
