Book lung

book lung \ˈbuk-ˌləŋ\ noun: a saccular breathing organ in many arachnids containing thin folds of membrane arranged like the leaves of a book

Etymology: from the organ’s similarity in shape to a book and similarity in function to a lung

Book lung conjures so many poetic images and associations that each mind can spin off on its own tangents.
