spiracles
Black widows breathe through small openings on the underside of their abdomen called spiracles, which allow air to enter their respiratory system. They do not have lungs; instead, they have book lungs that help them exchange gases.

Spider lungs are called "book lungs" because their structure resembles the pages of a book. These specialized respiratory organs consist of stacked, thin membranes that create a large surface area for gas exchange, similar to how pages in a book are stacked. This design allows spiders to efficiently extract oxygen from the air while minimizing water loss, making them well-suited for their environments. The term reflects both the anatomical appearance and the function of these lungs.
