Josef Hyrtl
Josef Hyrtl (7 December 1810 – 17 July 1894) was an Austrian anatomist. Biography Hyrtl was born at Kismarton, Hungary (now Eisenstadt, Austria). He began his medical studies in Vienna in 1831, having received his preliminary education in his native town. His parents were poor, and he had to find funds to defray the expenses of his medical education. In 1833, while he was still a student, he was named prosector in anatomy, and the preparations which this position required him to make for teaching purposes attracted the attention of professors as well as students. His graduation thesis, ''Antiquitates anatomicæ rariores'', was a prophecy of the work to which his life was to be devoted. On graduation he became Prof. Czermak's assistant (famulus) and later became also the curator of the museum. He added valuable treasures to the museum by the preparations which he made for it. As a student he set up a little laboratory and dissecting room in his lodgings, and his injections o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Catfish
The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species. Taxonomy The relationships of this family are not yet clear. Two of the genera, '' Gogo'' and '' Ancharius'', have been moved to a separate family called Anchariidae. The Ariidae are divided into three subfamilies: ''Galeichthys'' is the only genus classified in the subfamily Galeichthyinae and similarly '' Bagre'' is the only genus in the subfamily Bagreinae, while the rest of the genera are classified in the subfamily Ariinae. Previously, the family Ariidae has been grouped in the superfamily Doradoidea, but then it was moved into Bagroidea (along with Austroglanididae, Claroteidae, Schilbeidae, Pangasiidae, Bagridae, Malapteruridae, and Pimelodidae. It has also been classified in a superfamily Arioidea containing Ariidae and Anchariidae. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after Indian subcontinent, India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' (Atlantic Ocean, Atlantic) before the Pacific Ocean, Pacific was surmised. Conversely, Ming treasure voyages, Chinese explorers in the Indian Oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle East
The Middle East ( ar, الشرق الأوسط, ISO 233: ) is a geopolitical region commonly encompassing Arabian Peninsula, Arabia (including the Arabian Peninsula and Bahrain), Anatolia, Asia Minor (Asian part of Turkey except Hatay Province), East Thrace (European part of Turkey), Egypt, Iran, the Levant (including Syria (region), Ash-Shām and Cyprus), Mesopotamia (modern-day Iraq), and the Socotra Governorate, Socotra Archipelago (a part of Yemen). The term came into widespread usage as a replacement of the term Near East (as opposed to the Far East) beginning in the early 20th century. The term "Middle East" has led to some confusion over its changing definitions, and has been viewed by some to be discriminatory or too Eurocentrism, Eurocentric. The region includes the vast majority of the territories included in the closely associated definition of Western Asia (including Iran), but without the South Caucasus, and additionally includes all of Egypt (not just the Sina ...

Arius (fish)
''Arius'' is a genus of catfishes (order Siluriformes) of the family Ariidae. The genus ''Arius'' is distributed in brackish and fresh waters of Eastern Africa and south to Southeast Asia. Defining the limits so that ''Arius'' can form a natural grouping has always been a problem. The genus was never properly defined, and many species previously classified in ''Arius'' are now in other genera. Recent authors have recognized this genus as non monophyetic, rejecting that the genus is a natural grouping. Two unnamed groups are distinguished by accessory tooth plates, which are either very elongated and bearing molar-like teeth, or are oval shaped or subtriangular and bearing acicular (needle-like) or conic teeth. ''A. jatius'' lacks these tooth plates, but has been included in this genus based on its adipose fin and lateral line. The recognition of ''Arenarius'' as a junior synonym of ''Arius'' is tentative and needs to be further investigated. ''Arius'' species have three pairs of ...
