Postembryonic Development

Part of the Adaptations of Desert Organisms book series (DESERT ORGAN.)


As with embryogenesis (Chap. 2), the postembryonic development of terrestrial arthropods is highly modified and diverse among the various taxa. If all of the body segments (somites) are not present at hatching, additional segments are added anterior to the last segment at subsequent molts. This type of developmental pattern in which new segments are added to the body during certain molts is referred to as anamorphic and is common in many groups of arthropods including myriapoda and arachnids (Snodgrass 1952; Manton 1958; Butt 1960; Anderson 1973; Brusca 1975; Ruppert and Barnes 1994). At hatching, arthropods typically emerge as a larva, and larval forms can vary considerably among different arthropod groups. This chapter will discuss postembryonic development in some of the major representatives of the desert arthropods, especially in those groups which typify distinct patterns and for which sufficient information is available.
