Arachnidae
Arachnidae is a class of joint-legged invertebrate animals in the phylum Arthropoda, including spiders, scorpions, ticks, and mites. Members of this class typically have eight legs and a body divided into two segments - the cephalothorax and the abdomen. Arachnids are predominantly carnivorous, using venom or silk to capture their prey. They play a crucial role in ecosystems as both predators and scavengers, contributing to the balance of insect populations. Many arachnids are capable of producing silk for web-building or burrow construction.
