No for arthropods; yes for some molluscs. The larger aquatic arthropods like lobsters and crabs accomplish gas exchange using gills. Smaller ones like the land-based insects have holes (spiracles) in the exoskeleton and a tube system to facilitate gas exchange necessary for respiration. In this case, unlike mammals which use lungs to oxgenate blood which is pumped to the tissues, the tracheal tubes from the spiracles deliver oxygen directly to the tissues. Aquatic molluscs have gills for gas exchange whereas molluscs adapted to live on land like snails do have a lung.

What do mollusks have in common with arthopods?
Arthropods have the common characteristics of exoskeletons made of chitin, necessitating the further characteristics of segmented bodies and joint appendages. The phylum's name arthropoda comes from the greek meaning jointed legs or feet.
What type of arthropods is a woodlouse?
Woodlice are crustaceans, like crabs and lobsters. They have gills like them, not lungs, so they only live in damp places!
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.

How many mollusks are there in the world?
There are over 50,000 known species of Mollusks! That figure makes them second only to the Arthropods in invertebrate phylum size.
Is a lobster a echinoderms or a mollusks?
Lobsters are neither echinoderms nor mollusks like clams. They are also not arachnids. Instead, they are crustaceans, a subsection of arthropods.
Do mollusks that live in the water have lungs?
No, they don't.
