Spiders

Definition of Spiders as it relates to Animals, Arachnids, Opiliones, Araneae

Spiders, as members of the Araneae order, are air-breathing arachnids characterized by the presence of two main body parts - a cephalothorax and an abdomen. They possess four pairs of legs and use their fangs to inject venom into prey, which they then liquefy with digestive enzymes before consuming. Spiders are known for their intricate webs, which they use to catch insects and other small animals. Their silk-producing glands, located in the abdomen, are highly versatile and also serve various functions such as forming egg sacs or providing a means of transportation for juveniles. Spiders play a crucial role in controlling insect populations and maintaining ecological balance. In the hierarchy of Arachnids, Opiliones (also known as harvestmen) precede Spiders within the Animals category, highlighting their close relationship to other arachnids while still possessing unique characteristics that distinguish them from other orders.
