Ingvar Byrkjedal
Ingvar or Yngvar ( , d. early 7th century) was the son of Östen and reclaimed the Swedish throne for the House of Yngling after the Swedes had rebelled against Sölve. He is reported to have fallen in battle in Estonia and been buried there. Although the account of Ingvar is semi-legendary, the discovery of two boat grave sites in Salme, modern Estonia has confirmed that a similar historic event took place in the 8th century. ''Ynglinga saga'' Snorri Sturluson relates in his ''Ynglinga saga'' that King Ingvar, Östen's son, was a great warrior who often spent time patrolling the shores of his kingdom fighting Danes and Estonian vikings (''Víkingr frá Esthland''). King Ingvar finally came to a peace agreement with the Danes and could take care of the Estonian vikings. He consequently started pillaging in Estonia in retribution, and one summer he arrived at a place called Stein (see also Sveigder). The Estonians (''sýslu kind'') assembled a great army in the interior and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slickhead
Slickheads, also known as nakedheads or smoothheads, are deep water fishes that belong to the family Alepocephalidae. They are most commonly found in the bathypelagic layer, which is approximately 3000m below the surface. They get their name from the lack of scales on their heads. Similarly, the scientific name is from the Greek ᾰ̓- (''a''-, "not"); λέπος (''lepos'', "scale"); and κεφαλή (''kephalē'', "head"). It has about 22 genera with ca. 96 species. The only known fossil genus is '' Carpathichthys'' from the Early Oligocene of Poland, although an undescribed species of ''Bathyprion'' and several indeterminate taxa are also known from the same formation. Fossil otoliths are also known, dating to the Early Eocene. Genera Alepocephalidae contains the following extant genera: * '' Alepocephalus'' Risso, 1820 * ''Asquamiceps'' Zugmayer, 1911 * ''Aulastomatomorpha'' Alcock, 1890 * ''Bajacalifornia'' Townsend & Nichols, 1925 * ''Bathylaco'' Goode & T.

Leptoderma
''Leptoderma'' is a genus of slickheads found in the deep waters of the ocean The ocean is the body of salt water that covers approximately 70.8% of Earth. The ocean is conventionally divided into large bodies of water, which are also referred to as ''oceans'' (the Pacific, Atlantic, Indian Ocean, Indian, Southern Ocean ...s.

Taxa Named By Ingvar Byrkjedal
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
