Chanos (fish)
The milkfish (''Chanos chanos'') is the sole living species in the family Chanidae. However, there are at least five extinct genera from the Cretaceous. The repeating scientific name (tautonym) is from Greek ( ‘mouth’). The species has many common names. The Hawaiian name for the fish is ''awa'', and in Tahitian it is ''ava''. It is called ''bangús'' in the Philippines, where it is popularly known as the national fish, although the National Commission for Culture and the Arts has stated that this is not the case as it has no basis in Philippine law. In the Nauruan language, it is referred to as . Milkfish is also called ''bandeng'' or ''bolu'' in Indonesia. ''Chanos chanos'' occurs in the Indian Ocean and across the Pacific Ocean, from South Africa to Hawaii and the Marquesas, from California to the Galapagos, north to Japan, south to Australia. A single specimen was reported in 2012 in the eastern Mediterranean Sea. Milkfishes commonly live in tropical offshore marine ...

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Fishes Of The World
''Fishes of the World'' by the American ichthyologist Joseph S. Nelson (1937–2011) is a standard reference for fish systematics. Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science. The book begins with a general overview of ichthyology, although it is not self-contained. After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion. Each family (biology), family gets at least one paragraph, and usually a body outline drawing; large families have subfamilies and tribes described as well. Notable genera and species are mentioned, while the book generally does not deal with the species-level diversity. The complexities of the higher taxa are described succinctly, with many references for difficult points. The book does not involve color illustrations. The fourth edition was the first to incorporate the wide use of DNA analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

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] |
Nauruan Language
The Nauruan or Nauru language () is an Austronesian language, spoken natively in the island country of Nauru. Its relationship to the other Micronesian languages is not well understood. Phonology Consonants Nauruan has 16–17 consonant phonemes. Nauruan makes phonemic contrasts between velarized and palatalized labial consonants. Velarization is not apparent before long back vowels and palatalization is not apparent before non-low front vowels. Voiceless stops are geminated and nasals also contrast in length. Dental stops and become and respectively before high front vowels. The approximants become fricatives in "emphatic pronunciation." transcribes them as and but also remarks that they contrast with the non-syllabic allophones of the high vowels. Depending on stress, may be a flap or a trill. The precise phonetic nature of is unknown. transcribes it as and speculates that it may pattern like palatalized consonants and be partially devoiced.

National Commission For Culture And The Arts
The National Commission for Culture and the Arts of the Philippines ( fil, Pambansang Komisyon para sa Kultura at mga Sining, ceb, Nasodnong Komisyon alang sa Budaya ug mga Arte) is the official government agency for culture in the Philippines. It is the overall policy making body, coordinating, and grants giving agency for the preservation, development and promotion of Philippine arts and culture; an executing agency for the policies it formulates; and task to administering the National Endowment Fund for Culture and the Arts (NEFCA) – fund exclusively for the implementation of culture and arts programs and projects. History The successful overthrow of the dictatorship in 1986 through the People Power Revolution inspired the different sectors of society to rally behind the new government towards the restoration of democracy. On March 12, 1986, the Alliance of Artists for the Creation of a Ministry of Culture (AACMC) drafted and adopted a proposal for the establishment of a ...

Hawaiian Language
Hawaiian (', ) is a Polynesian language of the Austronesian language family that takes its name from Hawaii, the largest island in the tropical North Pacific archipelago where it developed. Hawaiian, along with English, is an official language of the US state of Hawaii. King Kamehameha III established the first Hawaiian-language constitution in 1839 and 1840. For various reasons, including territorial legislation establishing English as the official language in schools, the number of native speakers of Hawaiian gradually decreased during the period from the 1830s to the 1950s. Hawaiian was essentially displaced by English on six of seven inhabited islands. In 2001, native speakers of Hawaiian amounted to less than 0.1% of the statewide population. Linguists were unsure if Hawaiian and other endangered languages would survive. Nevertheless, from around 1949 to the present day, there has been a gradual increase in attention to and promotion of the language. Public Hawaiian-langua ...

Tautonym
A tautonym is a scientific name of a species in which both parts of the name have the same spelling, such as ''Rattus rattus''. The first part of the name is the name of the genus and the second part is referred to as the ''specific epithet'' in the ''International Code of Nomenclature for algae, fungi, and plants'' and the ''specific name'' in the ''International Code of Zoological Nomenclature''. Tautonymy (i.e., the usage of tautonymous names) is permissible in zoological nomenclature (see List of tautonyms for examples). In past editions of the zoological Code, the term tautonym was used, but it has now been replaced by the more inclusive "tautonymous names"; these include trinomial names such as ''Gorilla gorilla gorilla'' and '' Bison bison bison''. For animals, a tautonym implicitly (though not always) indicates that the species is the type species of its genus. This can also be indicated by a species name with the specific epithet ''typus'' or ''typicus'', although more c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
