  2. Aquatic respiration - Wikipedia

    en.wikipedia.org/wiki/Aquatic_respiration

    Aquatic arthropods generally possess some form of gills in which gas exchange takes place by diffusing through the exoskeleton. Others may breathe atmospheric air while remaining submerged, via breathing tubes or trapped air bubbles, though some aquatic insects may remain submerged indefinitely and respire using a plastron. A number of insects ...

  3. Discontinuous gas exchange - Wikipedia

    en.wikipedia.org/wiki/Discontinuous_gas_exchange

    The strolling arthropods hypothesis was a very early hypothesis for the evolution of discontinuous gas exchange cycles. [2] It was postulated that discontinuous gas exchange cycles and spiracles which close off the respiratory system , may in part do so to prevent small arthropod parasites such as mites and particulate matter such as dust from ...

  4. Mandibulata - Wikipedia

    en.wikipedia.org/wiki/Mandibulata

    The mandibulates are divided between the extant groups Myriapoda (millipedes & centipedes, among others) and Pancrustacea (including insects and crustaceans, among others). Molecular phylogenetic studies suggest that the living arthropods are related as shown in the cladogram below.

  5. Respiratory system of insects - Wikipedia

    en.wikipedia.org/wiki/Respiratory_system_of_insects

    Aquatic insects consume the stored air while under water or use it to regulate buoyancy. During a molt, air sacs fill and enlarge as the insect breaks free of the old exoskeleton and expands a new one. Between molts, the air sacs provide room for new growth—shrinking in volume as they are compressed by expansion of internal organs.

  6. Isopoda - Wikipedia

    en.wikipedia.org/wiki/Isopoda

    Isopoda is an order of crustaceans.Members of this group are called isopods and include both aquatic species, and terrestrial species such as woodlice.All have rigid, segmented exoskeletons, two pairs of antennae, seven pairs of jointed limbs on the thorax, and five pairs of branching appendages on the abdomen that are used in respiration.

  7. Entognatha - Wikipedia

    en.wikipedia.org/wiki/Entognatha

    These minute arthropods are apterous, unlike some orders of insects that have lost their wings secondarily (but are derived from winged ancestors). Their mouthparts are enclosed within a pouch in the head capsule, called the gnathal pouch, so only the tips of the mandibles and maxillae are exposed beyond the cavity. [1]

  9. Aquatic insect - Wikipedia

    en.wikipedia.org/wiki/Aquatic_insect

    Aquatic insects live mostly in freshwater habitats, and there are very few marine insect species. [9] The only true examples of pelagic insects are the sea skaters , which belongs to the order Hemiptera, and there are a few types of insects that live in the intertidal zone , including larvae of caddisflies from the family Chathamiidae , [ 10 ...
