Melon Butterflyfish
The melon butterflyfish (''Chaetodon trifasciatus'') or the Indian redfin butterflyfish, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the Indian Ocean from East Africa to Western Java. This is one species of a closely related group which includes the blacktail butterflyfish (''C. austriacus'') of the Red Sea and Gulf of Aden and the oval butterflyfish (''C. lunulatus'') which is found in the western Pacific, from eastern coasts of the Indonesian islands to Australia. Melon butterflyfish should not be confused with chevron butterflyfish (''C. trifascialis''), three-striped butterflyfish (''C. tricinctus''), or three-banded butterflyfish (''C. robustus''). Description and characteristics The oval butterflyfish and the blacktail butterflyfish resemble ''C. trifasciatus'' in coloration. The former has a less conspicuous back patch below the dorsal fin and a mainly dark anal fin, while the latter has black caudal and ...

Mungo Park (explorer)
Mungo Park (11 September 1771 – 1806) was a Scottish explorer of West Africa. After an exploration of the upper Niger River around 1796, he wrote a popular and influential travel book titled ''Travels in the Interior Districts of Africa'' in which he theorized the Niger and Congo merged to become the same river. He was killed during a second expedition, having successfully traveled about two-thirds of the way down the Niger. With Park's death, the idea of a Niger-Congo merger remained an open question although it became the leading theory among geographers. The mystery of the Niger's course, which had been speculated about since the Ancient Greeks and was second only to the mystery of the Nile's source, was not solved for another 25 years, in 1830, when it was discovered the Niger and Congo were in fact separate rivers. If the African Association was the "beginning of the age of African exploration" then Mungo Park was its first successful explorer; he set a standard for al ...

Gulf Of Aden
The Gulf of Aden ( ar, خليج عدن, so, Gacanka Cadmeed 𐒅𐒖𐒐𐒕𐒌 𐒋𐒖𐒆𐒗𐒒) is a deepwater gulf of the Indian Ocean between Yemen to the north, the Arabian Sea to the east, Djibouti to the west, and the Guardafui Channel, Socotra and Somalia to the south. In the northwest, it connects with the Red Sea through the Bab-el-Mandeb strait, and it connects with the Arabian Sea to the east. To the west, it narrows into the Gulf of Tadjoura in Djibouti. The ancient Greeks regarded the gulf as one of the most important parts of the Erythraean Sea. It later came to be dominated by Muslims, as the area around the gulf converted to Islam. From the late 1960s onwards, there started to be an increased Soviet naval presence in the Gulf. The importance of the Gulf of Aden declined when the Suez Canal was closed, but it was revitalized when the canal was reopened in 1975, after being deepened and widened by the Egyptian government. The waterway is part of the importa ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Chaetodon Trifasciatus Landaagiraavaru
''Chaetodon'' is a tropical fish genus in the family Chaetodontidae. Like their relatives, they are known as "butterflyfish". This genus is by far the largest among the Chaetodontidae, with about 90 living species included here, though most might warrant recognition as distinct genera. Species There are currently 87 recognized species in this genus: ''Chaetodon sensu stricto'' * '' Chaetodon capistratus'' Linnaeus, 1758 (Foureye butterflyfish) * '' Chaetodon ocellatus'' Bloch, 1787 (Spotfin butterflyfish) * '' Chaetodon striatus'' Linnaeus, 1758 (Banded butterflyfish) ''C. robustus'' group * '' Chaetodon hoefleri'' Steindachner, 1881 (Four-banded butterflyfish) * ''Chaetodon robustus'' Günther, 1860 (Three-banded butterflyfish) ''Lepidochaetodon'' group Image:Bep chaetodon punctatofasciatus.jpg, Spotband butterflyfish''Chaetodon (Exornator) punctatofasciatus'' Image:Chaetodon guttatissimus_01.jpg, Peppered butterflyfish''Chaetodon (Exornator) guttatissimus'' Image:8070 ...

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 ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ...
