Sudhausia
''Sudhausia'' is a genus of nematodes (roundworms) of the family Diplogastridae. They live in association with dung beetles and are primarily known from Africa. Species of ''Sudhausia'' show a suite of biological features that, together, are unusual for nematodes and animals in general: hermaphrodites, which are females in form, mature to produce offspring (eggs and larvae) before they are adults and thus even capable of mating, and their eggs grow in size during development. Hermaphrodites are also always live-bearing, which is unusual for nematodes under non-stressful conditions. The genus is named in honor of Walter Sudhaus, a German nematologist. Species *'' Sudhausia aristotokia'', associated with ''Onthophagus'' dung beetles in Ghana *'' Sudhausia crassa'', isolated from dung beetles of ''Onthophagus'' and the tribe Canthonini in South Africa and from ''Scarabaeus'' in Corsica *'' Sudhausia floridensis'', associated with ''Onthophagus'' dung beetles in Florida Flor ...

Diplogastridae
Diplogastridae, formerly Diplogasteridae, are a family of nematodes (roundworms) known from a wide range of habitats, often in commensal or parasitic associations with insects. Description Diplogastrid nematodes are characterized by a distinct "two-lobed" pharynx (hence their name from the Greek διπλόος = "double" and γαστήρ = "stomach"), the second ( posterior) lobe being composed mostly of glandular tissue. Most known species also have at least one tooth, which has presumably allowed them to access many new food sources compared with the related nematodes of Rhabditidae (including '' Caenorhabditis elegans''), most species of which feed on bacteria. Several diplogastrid species also have a polyphenism in their mouthparts, allowing resource specialization within species. The wide array of feeding modes in the Diplogastridae is reflected by the relatively high diversity and complexity of their mouth structures, which show accelerated rates of evolution in comparis ...

Corsica
Corsica ( , Upper , Southern ; it, Corsica; ; french: Corse ; lij, Còrsega; sc, Còssiga) is an island in the Mediterranean Sea and one of the 18 regions of France. It is the fourth-largest island in the Mediterranean and lies southeast of the French mainland, west of the Italian Peninsula and immediately north of the Italian island of Sardinia, which is the land mass nearest to it. A single chain of mountains makes up two-thirds of the island. , it had a population of 349,465. The island is a territorial collectivity of France. The regional capital is Ajaccio. Although the region is divided into two administrative departments, Haute-Corse and Corse-du-Sud, their respective regional and departmental territorial collectivities were merged on 1 January 2018 to form the single territorial collectivity of Corsica. As such, Corsica enjoys a greater degree of autonomy than other French regional collectivities; for example, the Corsican Assembly is permitted to exercise limit ...

Scarabaeus
The genus ''Scarabaeus'' consists of a number of Old World dung beetle species, including the "sacred scarab beetle", ''Scarabaeus sacer'' and typical of the tribe Scarabaeini. These beetles feed exclusively on dung, which they accomplish by rolling a piece of dung some distance from where it was deposited, and burying it in order to feed on it underground. They also prepare food for their larvae by excavating an underground chamber, and filling it with balls that have eggs laid in them. The growing larva feeds upon the dung ball, pupates, and eventually emerges as an adult. A "scarabaeus" is also a now outdated term (OED 2) for an object in the form of a scarab beetle in art. The scarab was a popular form of amulet in Ancient Egypt, and in ancient Greek art engraved gems were often carved as scarabs on the rest of the stone behind the main flattish face, which was used for sealing documents. A creature identified as Scarabaeus appears in "The Gold-Bug" by Edgar Allan P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Onthophagus
Gazella scarab ('' Onthophagus gazella'') males; note variation in horn size ''Onthophagus'' is a genus of dung beetles in the Onthophagini tribe of the wider scarab beetle family, Scarabaeidae. It is the most species-rich and widespread genus in the subfamily Scarabaeinae (the 'true' dung beetles), with a global distribution. Etymology The Genus name derives from the Greek ''onthos'', meaning dung, and ', meaning eater. Taxonomy This genus includes more than 20 subgenera and over 2,100 species. Some of the subgenera (including '' Proagoderus'', '' Diastellopalpus'', '' Digitonthophagus'', '' Strandius'', and '' Euonthophagus'') are now widely recognized as genera.

Live-bearing
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients by oophagy ...

Nematoda
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over time.
