Do aquatic arthropods exchange gases through a tracheal tubes b gills c their exoskeleton d book lungs?
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.
