Generalized Anatomy of a Spider
This illustration shows a generalized anatomy of arachnids, the group that includes scorpions, ticks, mites, and spiders. Among arachnids, only male spiders possess a copulatory organ on the pedipalp, an appendage at the anterior of the cephalothorax. The spider exudes its silk through the spinneret appendages at the tip of the abdomen, and then further draws it out using its legs. яндекс.ћетрика
