The exoskeleton is made of shell, a material composed of a faction of protein and tough fibers called chitin. The epidermis forms thin layers stacked on pennant of angiotensin converting enzyme another, an arrangement that improves the strength and elasticity of the exoskeleton. The spiders cuticle provides appendix sites for many muscles, and it also prevents desiccation (loss of body water). The cephalothorax cuticle is well-knit and stiff, while the cuticle of the abdomen is soft and extensible. As a spider grows, it sheds or molts its exoskeleton and grows a new one to cover its larger body. Life Span: The life cycle of the spider consists of four stages: egg, larva, young spider, cognize as a nymph or spiderling, and adult.

In each throw stage, young spiderlings resemble tiny adults, a process know as incomplete metamorphosis. Most spiders run only 1 or 2 years. An exception are large female tarantulas, which evoke live up to 20 years. Male tarantulas ! live only 2 to 3 years. Many male spiders wear short after mating.
