Spiders: Adaptations, Behaviors, and Life Cycle

Spiders are found globally except Antarctica, with 43,000 species. They are arachnids, related to scorpions and mites, and have evolved over 300 million years. Spiders are predatory, using venom and webs to catch prey. They have eight legs, fangs, and produce silk, which is strong and flexible. Webs serve various purposes, including hunting and protection. Some spiders are social, forming colonies. Reproduction involves complex rituals, and females may consume males post-mating. Spiderlings hatch from eggs and disperse to new areas. Lifespans vary by species.
