Freshwater Hatchetfish
The freshwater hatchetfish are a family, Gasteropelecidae, of ray-finned fish from South and Central America. The common hatchetfish is the most popular member among fish keeping hobbyists. The family includes three genera: ''Carnegiella'' (four species), ''Gasteropelecus'' (three species), and ''Thoracocharax'' (two species). Distribution and habitat Freshwater hatchetfish originate from Panama and South America (though they are absent from Chile). They tend to be an upper-level fish, often swimming directly below the surface of the water, biding their time patiently. Size When fully grown, freshwater hatchetfish range in size from 1 inch up to 2 1/2 inches. One exception is the Giant Hatchetfish Thoracocharax securis which can grow up to 3 1/2 inches. The smallest being the two species, the Pygmy hatchetfish Carnegiella myersi which only grows to about 0.9 inch (2.2 centimeters), the Dwarf Hatchetfish Carnegiella schereri which only grows to about 1 inch (2.6 centimeters). ...

Blackwinged Hatchetfish

Description Black-winged hatchetfish has a convex body. It has a very deep ventral profile with its anal fin set back. This species has wing-like pectoral fins that often extend to half of the fish's body length. In general, coloration is silver with black patches and stripes but, depending on the angle of light, colors may vary.

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C.

Pectoral 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 ...

Carnegiella Myersi
The pygmy hatchetfish (''Carnegiella myersi'') is a species of hatchetfish native to Peru. Named for ichthyologist George S. Myers George Sprague Myers (February 2, 1905 – November 4, 1985) was an American ichthyologist who spent most of his career at Stanford University. He served as the editor of ''Stanford Ichthyological Bulletin'' as well as president of the American So ...

It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south.
