About クモ類
Arachnids are a class of joint-legged invertebrates that includes spiders, scorpions, ticks, and mites. They are characterized by eight legs and a two-part body (cephalothorax and abdomen).
Arachnids have existed for over 400 million years and have adapted to every continent except Antarctica. Spiders are important predators that help control insect populations.
