Ranatrinae
Nepidae is a family of exclusively aquatic Heteropteran insects in the order Hemiptera. They are commonly called water scorpions for their superficial resemblance to scorpions, due to their raptorial forelegs and the presence of a long slender process at the posterior end of the abdomen, resembling a tail. There are 14 genera in the family, in two subfamilies, Nepinae and Ranatrinae. Members of the genus ''Ranatra'', the most widespread and species-rich genus, are sometimes called needle bugs or water stick insects as they are slenderer than ''Nepa''. While water scorpions do not sting with their tail, they do have a painful bite (strictly speaking a sting by their pointed proboscis), but this is much less harmful to humans than a true scorpion's sting. Range and habitat Nepidae are found on all continents except Antarctica. They mostly inhabit stagnant or slow-moving freshwater habitats like ponds, marshes, canals and streams. Exceptionally they have also been recorded from hyp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ranatra
''Ranatra'' is a genus of slender predatory insects of the family Nepidae, known as water scorpions or water stick-insects. There are around 100 ''Ranatra'' species found in freshwater habitats around the world, both in warm and temperate regions, with the highest diversity in South America (almost 50 species) and Asia (about 30 species, reviewed in 1972Lansbury I (1972) A review of the Oriental species of ''Ranatra'' Fabricius (Hemiptera-Heteroptera: Nepidae). ''Transactions of the Royal Entomological Society of London'', vol. 124, no. 3. 287-341.). Fewer are found elsewhere, but include several African, some in North America, three from Australia and three from the Palearctic, notably the relatively well-known European '' R. linearis''. Since ''Ranatra'' belongs to the family Nepidae which in turn belongs to the order Hemiptera, ranatrids are considered "true bugs". These brown insects are primarily found in stagnant or slow-moving water like ponds, marshes and canals, but can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cercotmetus
''Cercotmetus'' is a genus of water bugs in the subfamily Ranatrinae ("water stick-insects"). The recorded distribution of this genus is from is from mainland Asia to New Guinea and northern Australia. Description ''Cercotmetus'' species are similar to the related genus ''Ranatra'', but have distinctly shorter respiratory siphons (posterior breathing tubes, which are ¼ or less of the body length) and the front femur is shorter than length of the pronotum. Species The Global Biodiversity Information Facility lists: * ''Cercotmetus asiaticus'' Amyot & Serville, 1843 - type species * ''Cercotmetus brevipes'' Montandon, 1909 * ''Cercotmetus compositus'' Montandon, 1903 * ''Cercotmetus dissidens'' Montandon, 1911 * ''Cercotmetus fumosus'' Distant, 1904 * ''Cercotmetus horni'' Montandon, 1911 * ''Cercotmetus minutus'' Keffer & J.Polhemus, 1999 * ''Cercotmetus pilipes'' (Dallas, 1850) * ''Cercotmetus robustus'' Montandon, 1911 * ''Cercotmetus strangulatus ''Cercotmetus'' is a genu ...

Invertebrate Trachea
The trachea, also known as the windpipe, is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. The trachea extends from the larynx and branches into the two primary bronchi. At the top of the trachea the cricoid cartilage attaches it to the larynx. The trachea is formed by a number of horseshoe-shaped rings, joined together vertically by overlying ligaments, and by the trachealis muscle at their ends. The epiglottis closes the opening to the larynx during swallowing. The trachea begins to form in the second month of embryo development, becoming longer and more fixed in its position over time. It is epithelium lined with column-shaped cells that have hair-like extensions called cilia, with scattered goblet cells that produce protective mucins. The trachea can be affected by inflammation or infection, usually as a result of a viral illness affecting other parts of ...

Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Subfamily (biology)
In biological classification, a subfamily (Latin: ', plural ') is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end subfamily botanical names with "-oideae", and zoological names with "-inae". See also * International Code of Nomenclature for algae, fungi, and plants * International Code of Zoological Nomenclature * Rank (botany) * Rank (zoology) In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While olde ... Sources {{biology-stub ...

Tithonian
In the geological timescale, the Tithonian is the latest age of the Late Jurassic Epoch and the uppermost stage of the Upper Jurassic Series. It spans the time between 152.1 ± 4 Ma and 145.0 ± 4 Ma (million years ago). It is preceded by the Kimmeridgian and followed by the Berriasian (part of the Cretaceous).See for a detailed version of the geologic timescale Gradstein ''et al.'' (2004) Stratigraphic definitions The Tithonian was introduced in scientific literature by German stratigrapher Albert Oppel in 1865. The name Tithonian is unusual in geological stage names because it is derived from Greek mythology. Tithonus was the son of Laomedon of Troy and fell in love with Eos, the Greek goddess of dawn. His name was chosen by Albert Oppel for this stratigraphical stage because the Tithonian finds itself hand in hand with the dawn of the Cretaceous. The base of the Tithonian stage is at the base of the ammonite biozone of '' Hybonoticeras hybonotum''. A global reference profi ...

It shares borders with Eritrea to the north, Djibouti to the northeast, Somalia to the east and northeast, Kenya to the south, South Sudan to the west, and Sudan to the northwest. Ethiopia has a total area of . As of 2022, it is home to around 113.5 million inhabitants, making it the 13th-most populous country in the world and the 2nd-most populous in Africa after Nigeria. The national capital and largest city, Addis Ababa, lies several kilometres west of the East African Rift that splits the country into the African and Somali tectonic plates. Anatomically modern humans emerged from modern-day Ethiopia and set out to the Near East and elsewhere in the Middle Paleolithic period.
