To be classified in the class Arachnida, an arthropod must have the following characteristics. Arachnid bodies are usually divided into two distinct regions, the cephalothorax (anterior) and the abdomen (posterior). Adult arachnids have four pairs of legs, which attach to the cephalothorax. In immature stages, the arachnid may not have four pairs of legs (such as in mites).
