What do aquatic arthropods exchange gases through?
Most aquatic arthropods have external gills
Most aquatic arthropods reproduce by?
external sexual reproduction
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.
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 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.
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.
What distinguishes crustaceans from all other anthropods?
Crustaceans are distinguished from other arthropods in that their appendages are biramous (branch into two parts), and that they have a larval form which has a single eye and antennae used for swimming (nauplius). One might also assume they differ from most other arthropods in that they are aquatic, but there are both aquatic non-crustaceam arthropods (like the horseshoe crab and the sea spider), and non-aquatic crustaceans (like the terrestrial woodlouse). Note that the term "anthropod" should not be confused with arthropod - the former is a broad term and not a taxon, meaning human or human-like.
What is the difference between aguatic and terriestal?
It is not easy to compare terrestrial and aquatic systems because there is such on the similarities and differences between terrestrial and aquatic ecosystems.
