Brycinus Longipinnis
Primarily known as long-fin tetra, ''Brycinus longipinnis'' is also described as African long-finned tetra''among other terms Distribution ''Brycinus longipinnis'' is native to the western coastal regions of Africa from The Gambia to Democratic Republic of the Congo. It is found in the upper and lower reaches of big rivers and also in estuarine mixohaline waters. It is the only ''Brycinus'' species also to penetrate small rivers and streams. Description ''Brycinus longipinnis'' will grow to at least five inches (12.5 cm) long although most specimens are smaller than this. The populations in the small streams are smaller fish than those in the big rivers. Although it is essentially a freshwater fish, ''Brycinus longipinnis'' will live in brackish estuarine waters. Diet ''Brycinus longipinnis'' eats a wide range of animal and vegetable matter, including insect larvae, crustaceans and some algae. In the aquarium it will eat most fish foods including both flakes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Congo Tetra
The Congo tetra (''Phenacogrammus interruptus'') is a species of fish in the African tetra family, found in the central Congo River Basin in Africa. It is commonly kept in aquaria. Description The Congo tetra has a typical full-bodied tetra shape with rather large scales. When mature, the iridescent colors of the Congo tetra run through the fish from front to back, starting with blue on top changing to red through the middle, to yellow-gold, and back to blue just above the belly. It is not its fluorescent colors that make this tetra so distinct, but rather its tail fin, which develops into a grayish-violet feathery appendage with white edges. The males get up to 3.0 inches (8.5 cm). Females up to 2.75 inches (6 cm). The male is larger with more color, also the tail fin and dorsal fin are more extended. They also have different colors and extensions in the caudal fin. Aquarium trade and keeping Congo tetra are a popular aquarium species. However, their larg ...

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] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...
