  1. Arthropod - Wikipedia › wiki › Arthropod

    An arthropod (/ ˈɑːrθrəpɒd /, from Ancient Greek ἄρθρον (arthron) 'joint', and πούς (pous) 'foot' (gen. ποδός)) is an invertebrate animal having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, and crustaceans.

    Scientists know of more than 1 million speciesof arthropods. 80% of all known animal species are arthropods. Many more species have not yet been described. Most arthropod species are insects. "Insects are the most diverse organisms in the history of life". Most arthropods live on land. The phylum Arthropoda is the only phylum of invertebrates that mostly live on land. But crustaceans(crabs, shrimp and their relatives) mostly live in water. Arthropods are also the first phylum to develop genuine flight.

    Arthropods have a hard exoskeleton. The exoskeleton reduces the loss of water (dessication). This helps them to live on land without drying out.

    Arthropods are made up of four groups of living animals and one group of extinct animals: 1. Chelicerates include horseshoe crabs, spiders, mites, and scorpions. 2. Myriapods include millipedes and centipedes. 3. Crustaceans include lobsters, crabs, barnacles, crayfish and shrimp. Most crustaceans live in water. 4. Hexapods include insects and a few other organisms. Hexapodshave six legs. 5. Trilobites are a group of extinct arthropods. Trilobites all lived in oceans. Trilobites disappeared in the Permian–Triassic extinction event, about 252 million years ago. The trilobites are the second most famous type of fossils, after the dinosaurs.

  3. List of arthropod orders - Wikipedia › wiki › List_of_arthropod_orders

    Arthropods are invertebrate animals with a chitinous exoskeleton, segmented bodies, and jointed legs. The phylum Arthropoda contains numerous taxonomic orders in over 20 classes.

    The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments are of Latin origin, and may be confused with terms for bones: coxa, trochanter, femur, tibia, tarsus, ischium, metatarsus, carpus, dactylus, patella. Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods b

    The appendages of arthropods may be either biramous or uniramous. A uniramous limb comprises a single series of segments attached end-to-end. A biramous limb, however, branches into two, and each branch consists of a series of segments attached end-to-end.

    Arachnid legs differ from those of insects by the addition of two segments on either side of the tibia, the patella between the femur and the tibia, and the metatarsus between the tibia and the tarsus, making a total of seven segments.

    The legs of crustaceans are divided primitively into seven segments, which do not follow the naming system used in the other groups. They are: coxa, basis, ischium, merus, carpus, propodus, and dactylus. In some groups, some of the limb segments may be fused together. The claw of a lobster or crab is formed by the articulation of the dactylus against an outgrowth of the propodus. Crustacean limbs also differ in being biramous, whereas all other extant arthropods have uniramous limbs.

    Myriapods have seven-segmented walking legs, comprising coxa, trochanter, prefemur, femur, tibia, tarsus, and a tarsal claw. Myriapod legs show a variety of modifications in different groups. In all centipedes, the first pair of legs is modified into a pair of venomous fangs called forcipules. In most millipedes, one or two pairs of walking legs in adult males are modified into sperm-transferring structures called gonopods. In some millipedes, the first leg pair in males may be reduced to tiny h

    Insects and their relatives are hexapods, having six legs, connected to the thorax, each with five components. In order from the body they are the coxa, trochanter, femur, tibia, and tarsus. Each is a single segment, except the tarsus which can be from three to seven segments, each referred to as a tarsomere.

    Arthropod articles can be on any level that makes sense in context. Most will be about particular taxa. For example: 1. Regnum: Animalia 2. Phylum: Arthropoda 3. Subphylum: (if applicable) Crustacea 4. Class: Insecta, Arachnida, Malacostraca 5. Order: Lepidoptera, Araneae, Euphausiacea 6. Family: Papilionidae, Liphistiidae, Euphausiidae 7. Genus: Iphiclides, Heptathela, Euphausia 8. Species: Iphiclides podalirius, Kimura spider (Heptathela kimurai), Euphausia superba Other levels of taxonomy may be added if necessary : subclass, infraclass, suborder, infraorder, superfamily, subfamily, etc. In many cases, it makes sense to combine several taxonomic levels in a single article. For example, the genus Limulus contains only one species, Limulus polyphemus, so the one article covers both levels. Conversely, sometimes it is better to cover only a part of a taxon: mite deals with four different (but related) families and ignores the other families in the order Acari. Some large families, s...

    Stub templates

    Remember to mark up stubs with the appropriate template. Where specific templates do not exist (e.g. Merostomata, Pycnogonida, etc.), use {{arthropod-stub}}. Otherwise, see below.

    Talk pages and grading scheme

    Please place {{WikiProject Arthropods}} at the top of an article's talk page so articles can be assessed.What this template does: 1. It will help to lead new editors to this project. 2. If complete with quality and importance grading (see Article Classification and grading scheme), it helps us to stay on top of the huge number of arthropod-related articles.


    Please make sure to add articles to the appropriate categories among the ones listed at Category:Arthropods. If there are any categories that you think should be created, please request them here or on the talk page. In some cases, there might be more appropriate ways to group articles than categories, such as lists or article series boxes. For more information, see Wikipedia:Categories, lists, and series boxes.
