Heterotilapia
''Heterotilapia'' is a genus of cichlid fish that are native to rivers from Guinea-Bissau to Liberia in tropical West Africa. Formerly considered a subgenus of ''Tilapia'', in 2013, it was elevated to genus rank. They are medium-large cichlids, up to about in standard length depending on the species, and with a distinctive dark-and-light banded pattern. They are substrate spawners and brooders (not mouthbrooders as some other tilapias). ''H. buttikoferi'' is a common species that also has been introduced outside its native range, but ''H. cessiana'' is highly localized and critically endangered An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild.

Heterotilapia Buttikoferi
''Heterotilapia buttikoferi'', also known as the zebra tilapia, is a West African species of cichlid. Description ''H. buttikoferi'' is a large cichlid, capable of growing up to fish measurement, in standard length. Body is typically yellow or white with black stripes which can vary from very light to near black depending on the mood of the fish. The vertical black bars are broader than the lighter interspaces. Their stripes tend to fade as they age. Distribution and habitat This freshwater fish is native to large rivers in tropical West Africa from Guinea-Bissau to Liberia. People have imported and bred them in several other parts the world for aquarium or food purposes. ''H. buttikoferi'' is an alien species in Thailand where it has been introduced for use as an aquarium fish. There are reports that the species has spread at Srinakarin Dam, Kanchanaburi Province and Sirikit Dam, Uttaradit Province.

Tilapia
Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. Tilapia are mainly freshwater fish native to Africa and the Middle East, inhabiting shallow streams, ponds, rivers, and lakes, and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water. Traditionally a popular and affordable food in the Philippines with a mild taste, tilapia has been the fourth-most consume ...

Cichlidae
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 haplochrom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tilapia (genus)
''Tilapia'' is a genus of cichlid fishes endemic (ecology), endemic to freshwater habitats in Southern Africa. In the past this was a very large genus including all species with the common name tilapia, but today the vast majority are placed in other genera.Dunz, A.R., and Schliewen, U.K. (2013). ''Molecular phylogeny and revised classification of the haplotilapiine cichlid fishes formerly referred to as “Tilapia”.'' Molecular Phylogenetics and Evolution, online 29 March 2013. Species and taxonomy In the past, ''Oreochromis'' and ''Sarotherodon'' were retained in the genus ''Tilapia'', but these are treated as separate genera by all recent authorities.Nagl, S.; Tichy, H.; Mayer, W.E.; Samonte, I.E.; McAndrew, B.J., and Klein, J.

Ambrosius Hubrecht
Ambrosius Arnold Willem Hubrecht (2 March 1853, in Rotterdam – 21 March 1915, in Utrecht) was a Dutch zoologist. Among his prominent contributions was the evolution of placental mammals. Hubrecht studied zoology at Utrecht University with Harting and Donders, for periods joining Selenka in Leiden and later Erlangen, and Gegenbauer in Heidelberg. He graduated ''magna cum laude'' with Harting in 1874 with a study on nemertine worms. In 1875–1882 he worked at the ''Rijksmuseum van Natuurlijke Historie'' in Leiden, where he was the curator of ichthyology and herpetology, and in 1882 became professor at Utrecht. In 1890–1891 he traveled in Java, Sumatra, and Borneo, where he made embryological studies, notably on the tarsier. He visited the United States in 1896 and 1907. Honorary degrees were conferred on him by Princeton University, the University of St Andrews, the University of Dublin, the University of Glasgow ( LL.D 1901), and the University of Giessen.

Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Charles Tate Regan
Charles Tate Regan (1 February 1878 – 12 January 1943) was a British ichthyology, ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, London, Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Taxon described by him *See :Taxa named by Charles Tate Regan Among the species he described is the Siamese fighting fish (''Betta splendens'').

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
