Millipedes (originating from the Latin mille, "thousand", and pes, "foot") [1] [2] are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments ...
The band-tailed earthcreeper is thought to be monomgamous. It breeds in the austral summer, at least between September and January. It constructs a ball nest of thorny twigs with a side entrance to a tunnel leading to the nest chamber, typically placed about 1 to 2 m (3 to 7 ft) above the ground in a low bush or cactus.
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 ...
Symphylans, also known as garden centipedes or pseudocentipedes, are soil-dwelling arthropods of the class Symphyla in the subphylum Myriapoda. Symphylans resemble centipedes, but are very small, non-venomous, and may or may not form a clade with centipedes. [1] [2] More than 200 species are known worldwide. [3]

In attempting to determine its phylogenic relationships, Parvancorina has been compared with trilobite-like arthropods, such as Skania from the Burgess Shale Biota, Canada, and Primicaris from the Chengjiang Biota, China. [5] [6] However, the growth form of Parvancorina is unusual for an arthropod. [2]
Hematophagy evolved independently at least six times in arthropods living during the late Cretaceous; in ticks it is thought to have evolved 120 million years ago through adaptation to blood-feeding. [ 6 ] [ 40 ] This behavior evolved independently within the separate tick families as well, with differing host-tick interactions driving the ...
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are a part of the subphylum Crustacea (/ k r ə ˈ s t eɪ ʃ ə /), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice, krill, remipedes, isopods ...
