It is divided into two families, Habeliidae (monotypic, containing only Habelia), and Sanctacarididae (containing Sanctacaris, Utahcaris and Wisangocaris). They are thought to have been durophagous, with robust gnathobases (spined basal sections of limbs) used to shred hard-shelled organisms. Remains of trilobites have been found as stomach contents in Wisangocaris. Messorocaris has been suggested to be part of the order in some studies, but th

They are suggested to be stem-group chelicerates, though they lack the chelicerae present in true chelicerates. They may be the ancestral group from which modern chelicerates emerged.
