What consistent feature distinguishes the Class Arachnida, including wolf spiders?
Answer
Eight legs total
The classification step to the Class Arachnida is marked by a highly consistent morphological trait: the possession of exactly eight legs, arranged in four pairs. This feature serves as a primary distinction separating arachnids, which include spiders, scorpions, mites, and ticks, from insects (Class Insecta), which possess six legs. Furthermore, arachnids typically exhibit two main body parts, the cephalothorax (prosoma), where the legs are attached, and the abdomen (opisthosoma). Wolf spiders strictly adhere to this four-pair leg count attached to the fused head and thorax region.
