English: Four general modes of post-embryonic development are recognized in extant myriapods, including epimorphosis, euanamorphosis, hemianamorphosis, and teloanamorphosis. Of these, the first 3 modes are characterized by molts that occur throughout the life of the myriapods, while the last 3 modes, known as anamorphosis, are characterized by increasing the number of body segments. In epimorphosis, no addition of new body segments occurs at the time of molting. In euanamorphosis, every molt is characterized by the addition of new segments. In hemianamorphosis, initial molts are characterized by the addition of new segments but no further segments are added once a maximum number of segments is attained. In teloanamorphosis, molt and segment addition both cease at a certain stage and no further molts or segment addition occur thereafter.
