 Members of the families Huttoniidae, Palpimanidae and Stenochilidae have extensive scopulae on the sides of their often enlarged front legs, which enable them to both seize and manipulate prey.Members of the family Archaeidae have much smaller scopulae, but have a highly modified prosoma (cephalothorax), in which a long narrow "neck" separates a "head" portion from the rest of the prosoma.The long neck is matched by long chelicerae.
