An arthropod composed of eight legs and two body segments, without wings, uses spider web for hunting and life. The spider web is very sticky and tough, allowing prey to be captured effectively, and some species use venom to paralyze their prey. They inhabit various environments such as forests, grasslands, and around houses, and are classified as net spiders or long-jawed spiders depending on their hunting method.
