Adjacent to it there is the epidermis. Cuticle: the nonliving, and noncellular outer layer of an organism secreted by the underlying epidermis. Cuticles are common in a variety of animals including nematodes, annelids, and arthropods. The presence of a cuticle precludes the presence of cilia. Endocuticle: innermost layer of the arthropod procuticle consisting of proteins and chitin. Endocuticle is not hardened, or sclerotized, and there are no covalent interactions between the proteins and chitin. Endocuticle is digested and reused to build new procuticle during the molt. Not cross linked (less strong than exocuticle) Haemocoel: the principal body cavity in molluscs and arthropods, remnant of the blastocoel. It forms part of the open circulatory system found in these animals.
