Yes, spiders do need oxygen to survive. Like all living organisms, they require oxygen for cellular respiration, a process that generates the energy they need to function.
Spiders breathe through structures called book lungs or tracheae. Book lungs are layered structures that allow for gas exchange, while tracheae are a network of tiny tubes that directly deliver oxygen to their tissues. This adaptation is crucial as it enables spiders to thrive in various environments, including those with low oxygen levels.
Interestingly, spiders can survive for a limited time in low-oxygen environments, such as when they are submerged in water. However, they can’t survive indefinitely without oxygen. Overall, spiders exhibit fascinating adaptations that showcase their reliance on oxygen for survival.
