Gnathostoma
''Gnathostoma'' is a genus of parasitic nematodes. The species ''Gnathostoma spinigerum'' and ''Gnathostoma hispidum'' can cause gnathostomiasis. Neurognathostomiasis occurs in the USA. ''Gnathostoma binucleatum'' (which is native to the Americas) has not been previously reported to cause neurognathostomiasis, suggesting that ''G. spinigerum'' has been introduced to the Americas, but a survey of isolates has not confirmed this.

Nematodes
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. A 2013 survey of animal biodiversity published in the mega jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spirurida
Spirurida is an order of spirurian nematodes. Like all nematodes, they have neither a circulatory nor a respiratory system. Some Spirurida, like the genus ''Gongylonema'', can cause disease in humans. One such disease is a skin infection with Spirurida larvae, called "creeping disease". Some species are known as eyeworms and infect the orbital cavity of animal hosts. Systematics The Camallanida are sometimes included herein as a suborder, and the Drilonematida are sometimes placed here as a superfamily. There are doubts about the internal systematics of the Spirurida, and some groups placed herein might belong to other spirurian or even secernentean lineages.ToL (2002) The following superfamilies are at least provisionally placed in the Spirurida: * Acuarioidea * Aproctoidea * Diplotriaenoidea * Filarioidea * Gnathostomatoidea * Habronematoidea * Physalopteroidea * Rictularioidea * Spiruroidea * Thelazioidea Thelazioidea is a superfamily of spirurian nematodes in th ...

Cheiracanthus
''Cheiracanthus'' (from el, χείρ , 'hand' and el, ἄκανθα , 'spine') is an extinct genus of a group of fish called Acanthodii (or "spiny sharks"). It was a deep-bodied acanthodian about 12 in. (30 cm) in length. It had a blunt head, upturned tail, and fins protected by spines. Unlike many other acanthodians, it had one, solitary dorsal fin. ''Cheiracanthus'' swam at mid-depth in lakes and rivers, seizing small prey in its gaping jaws. Whole fossils of this fish occur only in Mid-Devonian rocks in Scotland, but its distinctive small, ornamented scales crop up around the world, as far south as Antarctica. See also * List of acanthodians This list of acanthodian genera is an attempt to create a comprehensive listing of all genera that have ever been included in the subclass Acanthodii, excluding purely vernacular terms. The list includes all commonly accepted genera, but also gen ... References Acanthodii genera Devonian fish of Antarctica Devonian fis ...

Tanqua
Tanqwa is a river of northern Ethiopia. Rising in the mountains of Dogu’a Tembien (2510 metres above sea level), it flows westward to Giba River which empties finally in the Tekezé River. Hydrography It is a confined river, locally meandering in its narrow alluvial plain, with a slope gradient of 25 metres per kilometre. With its tributaries, the river has cut a deep gorge. Tributaries Tributaries, upstream from Abiy Addi, include * Tsech'i River * May Qoqah * Arwadito * Adawro River Hydrology Hydrological characteristics The runoff footprint or annual total runoff volume is 41 million m³ at the bridge in Abiy Addi and 79 million m³ at the confluence with Giba River at Barashuwa. Peak discharges up to 543 m³ per second occur in the second part of the rainy season (month of August) when there are strong rains and the soils are saturated with water in many places. The percentage of total rainfall that directly leaves the catchment as storm runoff (also called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
