What Do Spiders Look Like?
Spiders are easily recognizable by their eight legs, two distinct body sections, and multiple eyes.

Their appearance varies widely, from the small jumping spider to larger orb weavers that build intricate webs to catch prey.Key Identifying Features
- Eight Legs: All spiders have four pairs of legs attached to their cephalothorax, distinguishing them from insects which have six legs.
- Body Structure: Spiders have two body sections—the cephalothorax (head and thorax combined) and the abdomen, connected by a thin waist.
- Multiple Eyes: Most spiders have eight eyes arranged in specific patterns, though the number and arrangement can vary by species.
- Specialized Mouthparts: Spiders have chelicerae (jaws) with fangs that inject venom to immobilize prey.
Notable Spider Species
Brown recluse and black widow spiders are the most concerning species in Tennessee due to their potentially harmful venom. The brown recluse is identified by its violin-shaped marking, while the black widow features a distinctive red hourglass shape on its abdomen. Unlike most harmless house spiders, these venomous species require professional identification and management.
