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 else can I help you with?
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.
Why are water striders classified as arthropods?
Water striders are classified as arthropods because of characteristics shared in common with other arthropods. It's important to remember the arthropod phylum (Arthropoda) is a very broad categorization of living things, characterized by jointed limbs, segmented bodies, and a hard exoskeleton. It includes all the insects. Water striders are considered "true bugs" or Hemiptera, along with aphids, shield bugs and leaf-hoppers; their order is classified below Insecta (the insect class).
What makes crustaceans different from all other arthropods?
Arachnids differ from other arthropods in that they have no antenna (nor wings, like many insects). They also use book lungs to breathe, rather than the gills or spiracle/trachea configuration. They have a body plan of only two sections (tagmata) and eight legs, although often with a modified forward pair different from most other arthropods.
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.
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 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 are three activities than exoskeleton makes more difficult for arthropods?
Exoskeletons can make certain activities challenging for arthropods, such as growth and molting, as they must shed their rigid outer layer to increase in size, which is a vulnerable period. Additionally, exoskeletons can limit flexibility and mobility, making rapid movements or intricate maneuvers more difficult. Finally, exoskeletons can hinder respiration in aquatic arthropods, as the rigid structure may restrict the efficient exchange of gases through gills.
How athropod can survive in land and water?
The major difference between arthropod survival on land and water would be their gas exchange method. Terrestrial methods include the book lungs such as in spiders and scorpions, or the tracheal gas delivery system through tubules connected to spiracles or openings in their exoskeletal segments, such as used by the insects. There are also some insects which are partly aquatic that "dive" below the water surface, and carry along with them air pockets from which they can use tracheal breathing. By contrast, aquatic arthropods like many crustaceans will use gills, or sometimes book gills. If gills are kept moist, they can live on both land and water providing moisture is present, a strategy used by crabs for example, when on land. For the smallest aquatic arthropods there is no dedicated gas exchange system, since their surface area to volume ratio is such that they can absorb oxygen directly from the water through their entire body surface.
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 is a crab is called mollusc?
Crab is not at all a mollusc. It belongs to Crustacea under the phylum Arthropoda. Crustaceans are mostly aquatic mandibulate arthropods that have a chitinous or calcareous and chitinous exoskeleton, a pair of often much modified appendages on each segment, and two pairs of antennae.
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 type of animal is a shellfish?
An aquatic animal, such as a mollusk or crustacean, that has a shell or shell-like exoskeleton.
