What are the different types of euarthropods?
Euarthropoda is typically subdivided into five subphyla, of which one is extinct: 1 Trilobites were an extinct group of formerly numerous marine animals that disappeared in the Permian–Triassic extinction event, though they were in decline prior to this killing blow, having been reduced to one order in the Late Devonian extinction. 2 Chelicerates include horseshoe crabs, spiders, mites, scorpions and related organisms characterized by the presence of chelicerae, appendages just above/in front of the mouthparts. Chelicerae appear in scorpions and horseshoe crabs as tiny claws that they use in feeding, but those of spiders have developed as fangs that inject venom. 3 Myriapods comprise millipedes, centipedes and their relatives, characterized by having numerous body segments each of which bearing one or two pairs of legs (or in a few cases being legless). They are sometimes grouped with the hexapods. 4 Crustaceans are primarily aquatic (a notable exception being woodlice, which is purely terrestrial) and are characterized by having biramous appendages. They include lobsters, crabs, barnacles, crayfish, shrimp and many others. 5 Hexapods comprise insects and three small orders of insect-like animals with six thoracic legs. They are sometimes grouped with the myriapods, in a group called Uniramia, though genetic evidence tends to support a closer relationship between hexapods and crustaceans.
