Ethmostigmus Rubripes
''Ethmostigmus rubripes'', the giant centipede, is the largest Australian centipede. Its size tends to vary in accordance with locality, with the head and body length ranging from 7.5 to over , with some individuals exceeding 20 cm. Coloration and patterning varies enormously between specimens from different locations, with shades of yellow and orange being perhaps the most common. Forms from arid climates are often a pale yellow in colour, while those from rainforest habitats typically exhibit dark green or blue coloration. Body proportion also varies with habitat; arid forms are typically very heavily built with proportionally short legs, while their tropical counterparts tend to have longer legs and a lighter build. ''Ethmostigmus rubripes'' also has three subspecies, with substantial variation within each. Habitat and range It is found in both dry and moist habitats, ranging from tropical rainforest to desert, usually in sheltered places such as under logs, leaf litter an ...

Johann Friedrich Von Brandt
Johann Friedrich von Brandt (25 May 1802 – 15 July 1879) was a German-Russian natural history, naturalist, who worked mostly in Russia. Brandt was born in Jüterbog and educated at a Gymnasium (school), gymnasium in Wittenberg and the Humboldt University of Berlin, University of Berlin. In 1831 he emigrated to Russia, and soon was appointed director of the Zoological Museum of the St Petersburg Academy of Sciences. Brandt encouraged the collection of native animals, many of which were not represented in the museum. Many specimens began to arrive from the expeditions of Nikolai Alekseevich Severtzov, Severtzov, Nikolai Przhevalsky, Przhevalsky, Aleksandr Fyodorovich Middendorf, Middendorff, Leopold von Schrenck, Schrenck and Gustav Radde. He described several birds collected by Russian explorers off the Pacific Coast of North America, including Brandt's cormorant, red-legged kittiwake and spectacled eider. As a paleontologist, Brandt ranks among the best. He was also an entomo ...

Forcipules
Forcipules are the modified, pincer-like, front legs of centipedes that are used to inject venom into prey. They are the only known examples of front legs acting as venom injectors. Nomenclature Forcipules go by a variety of names in both scientific and colloquial usages. They are sometimes known as poison claws or jaw legs, referencing their evolution from maxillipeds, a term which they are also sometimes known by in the context of centipedes (maxillipeds, maxillipedes). Other names include toxicognaths (from ''toxic'' + the Greek '' gnathos'', jaw), prehensors, telopodites, and forcipulae (singular forcipula). The term forcipule references their similarity with forceps. Anatomy, systematics, and variation Forcipules evolved from the maxillipeds, meaning the front legs of an arthropod, of centipedes' last common ancestor, believed to be somewhat Scutigeromorph-like. They were initially leg-like, then progressed into a more pincer or claw-like shape, as seen today, and res ...

Arthropods Of China
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and cuticle made of chitin, often mineralised with calcium carbonate. 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. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior organs; it has an open circulatory system. Like their exteriors, the internal organs of arthropods are generally built of repeated segments. Their nervous system is "ladder-lik ...
