Terrestrial arthropods primarily excrete nitrogenous waste in the form of uric acid, which conserves water and is less toxic, making it suitable for their drier environments. In contrast, aquatic arthropods generally excrete ammonia directly into the water, as it is highly soluble and can be diluted easily, reducing toxicity. This difference in excretion methods reflects their adaptation to diverse habitats, with terrestrial arthropods prioritizing water conservation.
What else can I help you with?
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 aquatic arthropods?
Some examples of aquatic arthropods include crabs, lobsters, shrimp, and barnacles. These animals have exoskeletons, jointed legs, and are important components of marine ecosystems.
Most aquatic arthropods reproduce by?
Most aquatic arthropods reproduce by laying eggs. These eggs can be deposited on structures in the water or carried by the female until they hatch. Some aquatic arthropods also undergo complex mating rituals or behaviors before reproducing.
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.
Why all arthropods are terrestrial?
Oh, they're not. Crustaceans are arthropods too, and they're aquatic. Almost all insect species fly. They're everywhere.
Is a grasshopper is invertebrate?
No. Grasshoppers are arthropods. Mollusks are usually aquatic, and do not resemble insects.
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 is the largest group of anthropods?
It is Insecta.The largest group of arthropods are aquatic, so things like shrimp, lobster, (and the most popular) Crab.Crab is the largest group in the arthropods.
Is crustaceans the same as arthropods?
Yes, crustaceans are a subgroup of arthropods. Arthropods are a diverse phylum that includes insects, arachnids, myriapods, and crustaceans, all characterized by their exoskeletons and jointed appendages. Crustaceans specifically include animals like crabs, lobsters, and shrimp, which primarily live in aquatic environments. Thus, while all crustaceans are arthropods, not all arthropods are crustaceans.
How do arthropods reproduces?
They lay an egg, and the egg hatches and is either a nymph or larva, then you should know what happens next!They reproduce sexually, and they reproduce asexually. In most terrestrial arthropods sexual reproduction is carried out internally. In most aquatic arthropods, sexual reproduction occurs externally.
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.
Which group of arthropods are marine?
The Crustacean group (usually considered a sub-phylum) are mostly marine arthropods, and include krill, shrimp, crabs and lobster; there are non-aquatic exceptions in this group like terrestrial woodlice.
