Cestraeus Plicatilis
The lobed river mullet (''Cestraeus plicatilis''), also known as ludong or banak, is a freshwater mullet. While it is claimed to be endemic to Cagayan River and tributaries extending through the watersheds of Cagayan Valley and the Santa-Abra River Systems of Ilocos Sur and Abra in the Philippines, verifiable and reliable sources have listed Celebes, New Caledonia, New Hebrides, and Fiji Fiji, officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about ... as areas where the lobed river mullet may be found. According to the BFAR, this fish is habituating in the deep pools of Addalem River in Aglipay, Quirino, and rapids of Didimpit in Lacab, Jones, Isabela. Description Ludong is herbivorous, eating only the filamentous algae that live on rocks and boulders in and near river rapids. A mature ...

Mullet (fish)
The mullets or grey mullets are a family (biology), family (Mugilidae) of ray-finned fish found worldwide in coastal temperate and tropical waters, and some species in fresh water. Mullets have served as an important source of food in Southern Europe, Mediterranean Europe since Roman Empire, Roman times. In ancient Egypt they ate pickled and dried mullet called fesikh. The family includes about 78 species in 26 genera. Mullets are distinguished by the presence of two separate dorsal fins, small triangular mouths, and the absence of a lateral line organ. They feed on detritus, and most species have unusually muscular stomachs and a complex pharynx to help in digestion. Classification and naming Taxonomy (biology), Taxonomically, the family is placed in the order Mugiliformes, which is named after it. Until recently, it was considered the only member of Mugiliformes, but more recent taxonomic treatments suggest that they are closely related to the Ambassidae, Asiatic glassfish ...

Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoology, zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "''Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, ... [...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] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 taxonomy (biology), 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. Phylogeneti ...

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Oceania
Oceania ( , ) is a region, geographical region including Australasia, Melanesia, Micronesia, and Polynesia. Outside of the English-speaking world, Oceania is generally considered a continent, while Mainland Australia is regarded as its continental landmass. Spanning the Eastern Hemisphere, Eastern and Western Hemisphere, Western hemispheres, at the centre of the land and water hemispheres, water hemisphere, Oceania is estimated to have a land area of about and a population of around 46.3 million as of 2024. Oceania is the smallest continent in land area and the list of continents and continental subregions by population, second-least populated after Antarctica. Oceania has a diverse mix of economies from the developed country, highly developed and globally competitive market economy, financial markets of Australia, French Polynesia, Hawaii, New Caledonia, and New Zealand, which rank high in quality of life and Human Development Index, to the much least developed countries ...

William John Macleay
Sir William John Macleay (13 June 1820 – 7 December 1891) was a Scottish-Australian politician, naturalist, zoologist, and herpetologist. Early life Macleay was born at Wick, Caithness, Scotland, second son of Kenneth Macleay of Keiss and his wife Barbara, ''née'' Horne. Macleay was educated at the Edinburgh Academy 1834–36 and then to studied medicine at the University of Edinburgh; but when he was 18 years old his widowed mother died, and he decided to go to Australia with his cousin, William Sharp MacLeay. They arrived at Sydney in March 1839 on HMS ''Royal George''. William Macleay took up land at first near Goulburn, and afterwards on the Murrumbidgee River. He is noted as the last of the naturalists in a family active in this field; his uncle was Alexander Macleay, Colonial Secretary of New South Wales from 1826 to 1836, and a member and fellow of societies concerned with the flora and fauna of the empire's colonies. Political career On 1 March 1855 Macleay w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
