Nguyễn Hữu Dực
Nguyễn (阮) (sometimes abbreviated as Ng̃) is the most common surname of the Vietnamese people. Outside of Vietnam, the surname is commonly rendered without diacritics as ''Nguyen''. By some estimates 30 to 39 percent of Vietnamese people bear this surname.Lê Trung Hoa, ''Họ và tên người Việt Nam'', NXB Khoa học - Xã hội, 2005 Origin and usage is the transcription of the Sino-Vietnamese pronunciation of the character 阮, which originally was used to write a name of a state in Gansu or ruan, an ancient Chinese instrument. The same Chinese character is often romanized as in Mandarin and as in Cantonese. The first recorded mention of a person surnamed Nguyễn is a description dating AD 317, of a journey to Giao Châu undertaken by Eastern Jin dynasty officer Nguyễn Phu and his family. Many events in Vietnamese history have contributed to the name's prominence. In 1232, after usurping the Lý dynasty, Trần Thủ Độ forced the descendants of the ...

Gastromyzontidae
The Gastromyzontidae are a family of loaches native to China and Southeast Asia, where typically found in streams and rivers with a fast current. The family includes about 137 species in eighteen genera Genus (; : genera ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses. In binomial nomenclature, the genus name forms the first part of the binomial s .... This family was resurrected by M. Kottelat in his review and revision of the loaches in 2012. They are commonly called hillstream loaches (a name shared with Balitoridae). Genera Gastromyzontidae contains the following genera: References Cypriniformes families {{Cypriniformes-stub ...

Vietnam
Vietnam, officially the Socialist Republic of Vietnam (SRV), is a country at the eastern edge of mainland Southeast Asia, with an area of about and a population of over 100 million, making it the world's List of countries and dependencies by population, fifteenth-most populous country. One of two communist states in Southeast Asia, Vietnam shares land borders with China to the north, and Laos and Cambodia to the west. It shares Maritime boundary, maritime borders with Thailand through the Gulf of Thailand, and the Philippines, Indonesia, and Malaysia through the South China Sea. Its capital is Hanoi and its largest city is Ho Chi Minh City. Vietnam was inhabited by the Paleolithic age, with states established in the first millennium BC on the Red River Delta in modern-day northern Vietnam. Before the Han dynasty's invasion, Vietnam was marked by a vibrant mix of religion, culture, and social norms. The Han dynasty annexed Northern and Central Vietnam, which were subs ...

Fish Described In 2005
A fish (: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are cold-blooded, their body temperature varying with the surrounding water, though some large active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communicate acoustically with each other, such as during courtship displays. The study of fish is known as ichthyology. The earliest fish appeared during the Cambrian as small filter feeders; they continued to evolve through the Paleozoic, diversifying into many forms. The earliest fish w ...

Sewellia
''Sewellia'' is a genus of fish in the family Gastromyzontidae. They are commonly called hillstream loaches (a common name shared with family Balitoridae) and are found in Laos and Vietnam.Kottelat, M. (2012)Conspectus cobitidum: an inventory of the loaches of the world (Teleostei: Cypriniformes: Cobitoidei). ''Raffles Bulletin of Zoology, Suppl. No. 26: 1-199.'' According to Roberts (1998) a possible defining characteristic of the genus ''Sewellia'' is their posterior pelvic valve is highly complex and different from other rheophilic loaches (loaches adapted to fast flowing water), their posterior pelvic valve involves the overlapping of the second to last ventrally exposed rays. Adapted to high velocity streams, ''Sewellia'' have depressed body shapes that are laterally expanded, thus increasing their hydrodynamical properties and allowing them to better stay attached to rocks in swift current. ''Sewellia'' also have paired fins with a single simple ray and numerous branched rays ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
