Mandibulata

Mandibulata, is one of two major clades of living arthropods alongside Chelicerata. It comprises the extant groups Myriapoda (millipedes & centipedes, among others) and Pancrustacea (including insects and crustaceans, among others). The name "Mandibulata" refers to the mandibles, a modified pair of limbs used in food processing, the presence of which are characteristic of most members of the group. Members of the group are referred to as mandibulates.

Subdivisions

Molecular phylogenetic studies suggest that the living arthropods are related as shown in the cladogram below. Crustaceans do not form a monophyletic group as insects and other hexapods have evolved from within them.[1][2][3]

Arthropoda
Mandibulata

Pancrustacea (crustaceans and hexapods)

Myriapoda (centipedes, millipedes, and allies)

Chelicerata (sea spiders, horseshoe crabs, and arachnids)
