What is the harvestmen domain?

The harvestmen domain, often referred to as Opiliones, is a group of arachnids that includes creatures commonly known as harvestmen or daddy longlegs. They are characterized by their long legs and small, rounded bodies, which are often fused with the cephalothorax, giving them a distinctive appearance. Harvestmen are typically found in moist environments and are known for their scavenging habits, feeding on decomposing plant material and small insects. Unlike Spiders, they do not produce silk and are harmless to humans.
