Insect cuticle is a layered, fibrous composite of chitin, water, protein, catechol, lipid and occasionally metal and mineral, secreted by a single layer of epidermal cells (Vincent and Wegst, 2004). Studies of the cuticle of Aspiculuris tetraptera with both the light and the electron microscopes have shown that there are three basic layers, namely the cortex, which consists In C. elegans, the major proteins in the cuticle are collagen-like proteins encoded by a large gene family with more than 150 members ( Cohen and Sundaram 2020 ).

The cuticle maintains the body shape, provides a strong layer against which muscles can act during locomotion and protects the nematode from the external environment. They are all similar in their basic structure, being composed of vitelline membrane, chitin and lipid layers, but there is considerable variability in the thickness of these layers. processes involved in the development of new cuticle.

Much is known about its chemical composition and uhrastructure (4,9,51,60, 63). The cuticle is an extracellular matrix consisting predominantly of small collagen-like proteins that are extensively crosslinked.
