Mandibles are often simply referred to as jaws. Mandibles are present in the extant subphylum subphyla Myriapoda millipedes and others , Crustacean Crustacea and Hexapoda insects etc. . These groups make up the clade Mandibulata , which is currently believed to be the sister group to the rest of arthropods, the clade Arachnomorpha Chelicerata Trilobite Trilobita . Unlike the chelicerae of arachnid s, mandibles can often be used to chew food. Mandibulates also differ by having Antenna biology antennae , and also by having three distinct body regions head, thorax and abdomen the prosoma of chelicerates is not a fusion of head and thorax, although often called a cephalothorax .
