The harvestmen have a small body with the cephalothorax and abdomen broadly joined, presenting two large eyes over a tubercle. Their legs are generally very large and thin. Some species live in the humus and have short legs and reduced eyes. Differently from other arachnids, they don't present mating courtship and the insemination is direct during the mating. The fertilized eggs are laid by an ovipositor and abandoned, like it happens in some insects.
