Books lungs are lung like organs found in arthropods. They function much like advanced lungs by exchanging atmospheric gases. Pockets of hemolymph pool in the lungs and are saturated by gases.
Well, honey, an animal that uses book lungs is a good ol' arachnid, like a spider or a scorpion. These critters have book lungs, which are basically a bunch of thin, flat plates stacked like pages in a book, allowing them to breathe. So, if you ever come across a spider reading a book, just know it's probably just trying to catch its breath.
Arthropods breathe primarily through three methods: tracheae, gills, and book lungs. Terrestrial arthropods, like insects, utilize a network of tracheae that deliver oxygen directly to tissues through small openings called spiracles. Aquatic arthropods, such as crustaceans, typically use gills to extract oxygen from water, while some arachnids, like spiders, possess book lungs that facilitate gas exchange through thin, stacked layers of tissue.
The arthropods are a phylum, a larger division than a class. Arthropoda has classes within it.
The Insecta class of arthropods may have wings. Insects are the only arthropods (and the only invertebrate) to have flight capability; but not all insects have wings.
Arthropods
Aquatic arthropods mostly exchange gases through (c) gills; some (like the horseshoe crabs) have book gills. The "book lungs" term usually applies to most arachnids like scorpions and spiders, which are terrestrial; most other terrestrial arthropods exchange gases through special holes in their segments called spiracles, attached to the tracheal tubules/tracheola which connect directly to the tissues.
Arthropoda is a phylum which is superior to class level .
Insects (class insecta) is the largest class of arthropods
