How does a spiders exoskeleton protect a spider?

A spider's exoskeleton serves as a protective barrier that shields its internal organs from physical damage and environmental hazards. Made of chitin, the exoskeleton is both strong and flexible, allowing Spiders to withstand impacts while maintaining mobility. Additionally, it helps prevent water loss, which is crucial for survival, especially in terrestrial environments. This tough outer layer also aids in defense against predators by providing a hard surface that is difficult to penetrate.
