How do spiders breathe if they do not have lungs like ours?
Quick Answer
Many spiders breathe through book lungs, tracheae, or both, depending on the species. These structures move oxygen into the body without true mammalian lungs.
The Full Story
Spiders use different respiratory systems from vertebrates. Some have book lungs, which are layered, leaflike structures that exchange gases efficiently, while others also have tracheal tubes that carry oxygen directly to tissues. Many spiders have both systems in some combination. These adaptations work well for a small-bodied animal with low oxygen demands compared with larger vertebrates.
