Amphilophus Zaliosus
''Amphilophus zaliosus'' is a species of cichlid that inhabits Lake Apoyo in Nicaragua. It is known in the aquarium trade as the arrow cichlid. It is an elongate species in the Midas cichlid species complex. The arrow cichlid shares its habitat with five other recently discovered species of this complex. Genetic evidence from Apoyo supports a hypothesis that the six known species of the lake evolved via sympatric speciation. Appearance The yellow background color, common among the ''Amphilophus'' cichlids of Nicaragua, is absent in the arrow cichlid. The background color is silver to greenish gray. Breeding specimens can be entirely black. Conservation The arrow cichlid is the only endemic Lake Apoyo cichlid that has been evaluated by the IUCN. It has been rated as Critically Endangered on the IUCN Red List. Among the small body of information regarding populations of the species of this group, four other species may have smaller populations and/or ranges than this fish in Lak ...

Amphilophus Flaveolus
''Amphilophus'' is a genus of cichlid fishes from Central America, ranging from southern Mexico to Panama. The genus currently contains 23 species, including several that are well known from the aquarium trade. However, studies led by Oldřich Říčan in 2008 and 2016 suggested that several species within ''Amphilophus'' should be moved to the genus ''Astatheros''. Species proposed to be moved to ''Astatheros'' in 2008 were ''A. alfari'', ''A. altifrons'', ''A. bussingi'', ''A. diquis'', ''A. longimanus'', ''A. macracanthus'' (which would be the type species for ''Astatheros''), ''A. margaritifer'', ''A. rhytisma'', ''A. robertsoni'' and ''A. rostratus''. Further genetic studies led Říčan to put ''A. macracanthus'' in ''Astatheros'', but to put ''A. alfari'', ''A. altifrons'', ''A. bussingi'', ''A. diquis'', ''A. longimanus'', ''A. rhytisma'', ''A. robertsoni'' and ''A. rostratus'' within the genus ''Cribroheros''. Říčan's study suggests that the ''Astatheros'' species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fish Of Nicaragua
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Freshwater Fish Of Nicaragua
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. Fresh water is the water resource that is of the most and immediate use to humans. Fresh water is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlid Fish Of Central America
Cichlids () are a large, diverse, and widespread family of percomorph fish in the family Cichlidae, order Cichliformes. At least 1,760 species have been scientifically described, making it one of the largest vertebrate families, with only the Cyprinidae being more speciose. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. They are native to the Neotropics, Africa (including Madagascar), the Middle East, and the Indian subcontinent, although some species have been introduced worldwide. Many cichlids, particularly tilapia, are important food fishes, while others, such as the '' Cichla'' species, are valued game fish. The family also includes many popular freshwater aquarium fish kept by hobbyists, including the angelfish, oscars, and discus. Cichlids have the largest number of endangered species among vertebrate families, most in the haplochromine gro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...
