Arthropods adapted to an aquatic environment that need to extract oxygen from water will have gills, for instance most (but not all) crustaceans, like crabs and lobsters. Crabs can come on land so long as their gills are kept moist; those that do usually seek out damp habitats.
What else can I help you with?
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.
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!
How do arthropods eliminate waste?
They have a mouth and an anus like most higher organisms for solid food waste. Gaseous waste for terrestrial arthropods passes through microscopic tubules (tracheoles) and out pairs of openings in body segments (the spiracles); for aquatic arthropods, gills are used to remove nitrogenous waste - particularly useful for highly toxic ammonia.
Do arthropods and mollusks have lungs?
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 eight characteristics are typical of arthropods?
Characteristics of arthropods: 1 - a hard outer body covering called an exoskeleton 2 - specialized mouth parts 3 - jointed legs 4 - compound eyes 5 - segmented body 6 - bilateral symmetry 7 - a tubular alimentary canal, with mouth and anus 8 - respiration by means of gills, tracheae and spiracles
Do all arthropods have gills?
yes
What do aquatic arthropods exchange gases through?
Aquatic arthropods typically exchange gases through gills. Gills are structures that are rich in blood vessels and provide a large surface area for gas exchange to occur, allowing the arthropods to extract oxygen from the water and release carbon dioxide.
What body parts do arthropods have that echinoderms do not have?
Gills and a well developed nervous system
Is the trachea found in all arthropods?
No, not all. Remember some arthropods are aquatic; the spiracle/trachea/tracheole system utilized by terrestrial insects is largely replaced by gills in marine arthropods.

How do terrestrials arthropods excrete metabolic wastes?
Terrestrial arthropods excrete metabolic wastes in the form of uric acid, which is solid and fairly dry. Aquatic arthropods excrete ammonia through gills or other membranes.
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 arthropods have spiracles?
The larvae form of amphibians live in water and have gills. When they grow into their adult form they develop lungs. There are three orders of amphibians, Urodela, Anura and Apoda. Some Urodela (e.g Axolotls) retain their gills as adults, other orders do not.
In which class of animals is venous heart found?
Venous hearts are found in certain invertebrates, particularly in some mollusks and arthropods. These hearts pump blood from the body cavity into the gills or other respiratory structures.

Why are arthropods called arthropods?
They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
