They are the largest order of arachnids and rank seventh in total species diversity
Myriapoda which are mutually exclusive, and all of which represent hypotheses of evolutionary relationships. Traditional relationships supported by morphological similarities (anatomical or developmental similarities) are challenged by newer relationships supported by molecular evidence (including DNA sequence and amino acid similarities). Myriapoda Myriapoda is a subphylum of arthropods containing millipedes, centipedes, and others. The group contains over 16,000 species, most of which are terrestrial. Although their name suggests they have myriad (10,000) legs, myriapods range from having up to 750 legs (the millipede "Illacme plenipes") to having fewer than ten legs. The fossil record of myriapods reaches back into the late Silurian,
