The abdomen is, at least posteriorly, distinctly jointed; the mandibles have three joints; the coxæ of the front legs form an auxiliary pair of maxillæ; eyes two, very rarely more or none; respiration through tracheæ; the sexes distinct. These creatures are commonly known as daddy-long-legs, and are found in all parts of the globe. They live on the ground and are predaceous, feeding usually on insects. The order is also called Opilionea, Opilionina, and Phalangidea.
