    The group is generally regarded as monophyletic, and many analyses support the placement of arthropods with cycloneuralians (or their constituent clades) in a superphylum Ecdysozoa. Overall, however, the basal relationships of animals are not yet well resolved. Likewise, the relationships between various arthropod groups are still actively debated.

    Arthropod eyes Head of a wasp with three ocelli (center), and compound eyes at the left and right. Most arthropods have sophisticated visual systems that include one or more usually both of compound eyes and pigment-cup ocelli ("little eyes"). In most cases, ocelli are only capable of detecting the direction from which light is coming, using ...

    en.wikipedia.org/wiki/List_of_arthropod_orders

    The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings.

  5. Microarthropods - Wikipedia

    en.wikipedia.org/wiki/Microarthropods

    The body, like all arthropods, is segmented (with jointed limbs). Microarthropods are found almost everywhere, most often in fallen leaves, soil litter and upper soil layers. They play an important role in accelerating the decomposition of organic matter and forming the soil structure. In water, they are part of the plankton or benthosa.

    [1] [2] Microfauna are represented in the animal kingdom (e.g. nematodes, small arthropods) and the protist kingdom (i.e. protozoans). A large amount of microfauna are soil microfauna which includes protists, rotifers, and nematodes. These types of animal-like protists are heterotrophic, largely feeding on bacteria.

  9. Arthropod exoskeleton - Wikipedia

    en.wikipedia.org/wiki/Arthropod_exoskeleton

    The arthropod exoskeleton is divided into different functional units, each comprising a series of grouped segments; such a group is called a tagma, and the tagmata are adapted to different functions in a given arthropod body. For example, tagmata of insects include the head, which is a fused capsule, the thorax as nearly a fixed capsule, and ...
