Scleropages
''Scleropages'' is a genus of fish in the family Osteoglossidae found in Asia and Australia. All of these species are carnivorous and have great jumping ability. These species are highly valued as aquarium fish, particularly by those from Asian cultures. In 2003, a study redescribed several naturally occurring color varieties of ''S. formosus'' into four separate species. The majority of researchers dispute these redescriptions, arguing that the published data are insufficient to justify recognizing more than one Southeast Asian species of ''Scleropages'' and that divergent haplotypes used to distinguish the color strains into isolated species were found within a single color strain, contradicting the findings. They are considered monotypic, consisting of closely related haplotypes based on color. The ancestor of the Australian arowanas: ''S. jardinii'' and ''S. leichardti'', diverged from the ancestor of the Asian arowanas about 140 million years ago, during the Early Cretaceous p ...

Scleropages Formosus
The Asian arowana (''Scleropages formosus'') comprises several phenotypic varieties of freshwater fish distributed geographically across Southeast Asia. While most consider the different varieties to belong to a single species, work by Pouyaud ''et al.'' (2003) differentiates these varieties into multiple species. They have several other common names, including Asian bonytongue, dragonfish, and a number of names specific to the different color varieties. Native to Southeast Asia, Asian arowanas inhabit blackwater rivers, slow-moving waters flowing through forested swamps and wetlands. Adults feed on other fish, while juveniles feed on insects. These popular aquarium fish have special cultural significance in areas influenced by Chinese culture. The name 'dragonfish' stems from their resemblance to the Chinese dragon. This popularity has had both positive and negative effects on their status as endangered species. Evolution and taxonomy Like all members of the Osteoglossidae ...

Scleropages Jardinii
''Scleropages jardinii'', the Gulf saratoga, Australian bonytongue , Pearl arowana or northern saratoga, is a freshwater bony fish native to Australia and New Guinea, one of two species of fishes sometimes known as Australian arowana, the other being ''Scleropages leichardti''. It has numerous other common names, including northern saratoga, toga and barramundi (not to be confused with the barramundi perch, ''Lates calcarifer''). It is a member of the subfamily Osteoglossinae, a ( basal) teleost group. Its scientific name is sometimes spelled ''S. jardini''. Distribution ''Scleropages jardinii'' is patchily distributed throughout most of the Gulf of Carpentaria drainage system, west to the Adelaide River in the Northern Territory, throughout northern Queensland and in central-southern New Guinea.Martin F.

Scleropages Inscriptus
The Batik Arowana (''Scleropages inscriptus''), is a large, bony-tongued fish native to Myanmar. The species is found in the Tanintharyi River basin on the Indian Ocean coast of peninsular Myanmar. This species is differentiated from other members of Scleropages by the wavy pattern present on the scales and head of the fish similar to Batik textiles. Past records indicate that the fish was a fairly commonly consumed fish in the region. However it is claimed to be extinct in the wild due to overharvesting for the aquarium trade.

Osteoglossidae
Osteoglossidae is a family of large freshwater fish, which includes the arowanas and arapaima. The family contains two subfamilies Arapaiminae and Osteoglossinae, with a total of five living genera. Osteoglossids are basal teleosts that originated some time during the Cretaceous, and are placed in the actinopterygiid order Osteoglossiformes. As traditionally defined, the family includes several extant species from South America, one from Africa, one from Asia, and two from Australia Australia, officially the Commonwealth of Australia, is a Sovereign state, sovereign country comprising the mainland of the Australia (continent), Australian continent, the island of Tasmania, and numerous List of islands of Australia, sma ....

Paleocene
The Paleocene, ( ) or Palaeocene, is a geological epoch (geology), epoch that lasted from about 66 to 56 mya (unit), million years ago (mya). It is the first epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name is a combination of the Ancient Greek ''palaiós'' meaning "old" and the Eocene Epoch (which succeeds the Paleocene), translating to "the old part of the Eocene". The epoch is bracketed by two major events in Earth's history. The K–Pg extinction event, brought on by Chicxulub impact, an asteroid impact and possibly volcanism, marked the beginning of the Paleocene and killed off 75% of living species, most famously the non-avian dinosaurs. The end of the epoch was marked by the Paleocene–Eocene Thermal Maximum (PETM), which was a major climatic event wherein about 2,500–4,500 gigatons of carbon were released into the atmosphere and ocean systems, causing a spike in global temperatures and ocean acidification.

William Saville-Kent
William Saville-Kent (10 July 1845 – 11 October 1908) was an English marine biologist and author. Early life Born in the town of Sidmouth in Devon, South West England on 10 July 1845, William Saville-Kent was the son of Samuel Saville Kent (7 July 1800 – 5 February 1872) and Mary Ann Windus (b. 1808 – May 1852), who was Samuel's first wife. William was the youngest of ten children from his father's first marriage. Samuel was employed as a "Factory Commissioner" for the Home Office, and inspected factories to ensure that they were properly implementing the worker safety measures regulated in the Factory Acts of 1833. As the acts sought to alleviate the harm done to children that were caused by unregulated working conditions in the factories, Samuel's “duties required him to inspect factories that employed women and children.” Despite having “ambitions for promotion,” Samuel “suffered from the effects of local gossip and disapproval,” as a consequence of him be ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
