Spiders are identified by their two body parts - a fused head and thorax, and their abdomen. Spiders have between six and eight eyes, eight legs, no wings, and no antennae. They do not have chewing mouthparts, but instead use digestive enzymes in their saliva to break down their food before consuming it. These arachnids come in a wide range of sizes and can vary drastically in appearance depending on their exact species. Some species are smooth and shiny while others are covered in hair. In addition, spiders come in a variety of colors including brown, tan, black, yellow, orange, and red. Lastly, many species of spiders have unique markings or patterns that help set them apart.
