Spiders die for many of the same reasons as other animals, such as hunger, dehydration, injury, predators, and harsh weather. Their small bodies are fragile, and the wrong conditions can quickly become deadly. Many spiders die naturally after reaching the end of their life cycle. Some species are more likely to survive everyday risks than…
