The newly hatched arachnid is small, and the exoskeleton is less sclerotized (hardened) than that of the adult. Dev. Significantly, cuticles of each stage differ in their surface protein expression, layer number, relative thickness, and composition, presumably to accommodate for the changing developmental needs and environmental conditions experienced during the life of the animal.

Two sets of interacting collagens form functionally distinct substructures within a Caenorhabditis elegans extracellular matrix. These molecules assemble into the relatively insoluble, higher-order complexes that form the cuticle matrix. With well over 15,000 species identified today, they can be found in different habitats ranging from terrestrial to marine environments. In WormBook (ed. The adult cuticle is approximately 0.5 μm in thickness (Cox et al., 1981a) and is organized into five major layers or zones: the surface coat, the epicuticle layer, and the cortical, medial and basal zones (Cox et al., 1981a; 1981b, Bird and Bird, 1991). Anchoring fibrils extend from FOs into the extracellular basal lamina, which is linked, in turn, to muscles through the M line and dense bodies of the sarcomere (Francis and Waterston, 1991; Hresko et al., 1994, 1999; Bercher et al., 2001; Hong et al., 2001; Hahn and Labouesse, 2001) (see also Somatic Muscle).
