Boat-billed Heron
The boat-billed heron (''Cochlearius cochlearius''), colloquially known as the boatbill, is an atypical member of the heron family. It is the only member of the genus ''Cochlearius'' and was formerly placed in a monotypic family, the Cochleariidae. It lives in mangrove swamps from Mexico south to Peru and Brazil. It is a nocturnal bird, and breeds semi colonially in mangrove trees, laying two to four bluish-white eggs in a twig nest. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the boat-billed heron in his ''Ornithologie'' based on a specimen collected in French Guiana. He used the French name ''La Cuillière'' and the Latin ''Cochlearius''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Brisson placed the species in a new genus ''Cochlearius'' (with the same name as that of the species). When in 1766 the Swedish naturalist Carl Linnaeus updated his ''System ...

Mathurin Jacques Brisson
Mathurin Jacques Brisson (; 30 April 1723 – 23 June 1806) was a French zoologist and natural philosopher. Brisson was born at Fontenay-le-Comte. The earlier part of his life was spent in the pursuit of natural history; his published works in this field included ''Le Règne animal'' (1756) and the highly regarded ''Ornithologie'' (1760). As a young man, he was a disciple and assistant of René Antoine Ferchault de Réaumur. For a period of time he was an instructor of physical sciences and natural history to the family of the monarch. He held the chair of physics at the College of Navarre, and from 1759 was a member of the Academy of Sciences. A significant work involving the "specific weight of bodies" was his ''Pesanteur Spécifique des Corps'' (1787). In his investigations of electricity, Brisson was opposed to the theories of Priestley and Franklin. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tautonym
A tautonym is a scientific name of a species in which both parts of the name have the same spelling, such as ''Rattus rattus''. The first part of the name is the name of the genus and the second part is referred to as the ''specific epithet'' in the ''International Code of Nomenclature for algae, fungi, and plants'' and the ''specific name'' in the ''International Code of Zoological Nomenclature''. Tautonymy (i.e., the usage of tautonymous names) is permissible in zoological nomenclature (see List of tautonyms for examples). In past editions of the zoological Code, the term tautonym was used, but it has now been replaced by the more inclusive "tautonymous names"; these include trinomial names such as ''Gorilla gorilla gorilla'' and '' Bison bison bison''. For animals, a tautonym implicitly (though not always) indicates that the species is the type species of its genus. This can also be indicated by a species name with the specific epithet ''typus'' or ''typicus'', although more c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Trinidad And Tobago
A total of 487 species of birds have been confirmed on the islands of Trinidad and Tobago. Of them, two are endemic, six have been introduced by humans, 130 are rare or vagrants, and 11 have been extirpated. The status of one more has not been determined. There are few places in the world where so many bird species can be seen in such a small area, many of them unique, very rare, or of particular interest. They range from the many species of hummingbird to the cave-dwelling oilbird (which uses echo-location to fly in the dark) and the scarlet ibis. The islands are within a few miles of Venezuela, and the species are therefore typical of tropical South America. However, the number of species is relatively low compared to the mainland, as would be expected on small islands. The resident breeding birds are augmented in the northern winter by migrants from North America, although the variety of migrant passerines is very limited compared to Central America.

Ardeidae
The herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 72 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genera ''Botaurus'' and ''Ixobrychus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, '' Ardea'' and ''Egretta''. Similarly, the relationships of the genera in the family are not completely resolved. However, one species formerly considered ...

Ariidae
The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species. Taxonomy The relationships of this family are not yet clear. Two of the genera, '' Gogo'' and '' Ancharius'', have been moved to a separate family called Anchariidae. The Ariidae are divided into three subfamilies: ''Galeichthys'' is the only genus classified in the subfamily Galeichthyinae and similarly '' Bagre'' is the only genus in the subfamily Bagreinae, while the rest of the genera are classified in the subfamily Ariinae. Previously, the family Ariidae has been grouped in the superfamily Doradoidea, but then it was moved into Bagroidea (along with Austroglanididae, Claroteidae, Schilbeidae, Pangasiidae, Bagridae, Malapteruridae, and Pimelodidae. It has also been classified in a superfamily Arioidea containing Ariidae and Anchariidae. Dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centropomus
''Centropomus'' is a genus of predominantly marine fish comprising the family Centropomidae. The type species is '' Centropomus undecimalis'', the common snook. Commonly known as snooks or ''róbalos'', the ''Centropomus'' species are native to tropical and subtropical waters of the western Atlantic and eastern Pacific Oceans. Prior to 2004, the subfamily Latinae, which contained three genera, was placed within the Centropomidae; this has since been raised to the family level and renamed Latidae because a cladistic analysis showed the old Centropomidae to be paraphyletic. This has left ''Centropomus'' as the only remaining genus in this family. These are popular game and food fish. Dating from the upper Cretaceous, the centropomids are of typical percoid shape, distinguished by having two-part dorsal fins, a lateral line that extends onto the tail, and frequently, a concave shape to the head. They range from in length and are found in tropical and subtropical waters. The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Penaeus
''Penaeus'' is a genus of prawns, including the giant tiger prawn (''P. monodon''), the most important species of farmed crustacean worldwide. The genus has been reorganised following a proposition of Pérez Farfante and Kensley based on morphological differences, in particular the genital characteristics of these animals, although this revision has not been universally accepted. Following the revision, many species formerly in the genus ''Penaeus'' have been reassigned to new genera in the family Penaeidae: ''Farfantepenaeus'', '' Fenneropenaeus'', ''Litopenaeus'' and ''Marsupenaeus''. The following table gives an overview: A few more species that are sometimes given as ''Penaeus'' spp. are actually assigned to the genus ''Melicertus ''Melicertus'' is a genus of "king" prawns, comprising eight species which were previously classified as members of the genus ''Penaeus'': *''Melicertus canaliculatus'' (Olivier, 1811) - witch prawn *''Melicertus hathor'' (Burkenroad, 1959) ...

Estuary
An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Estuaries form a transition zone between river environments and maritime environments and are an example of an ecotone. Estuaries are subject both to marine influences such as tides, waves, and the influx of saline water, and to fluvial influences such as flows of freshwater and sediment. The mixing of seawater and freshwater provides high levels of nutrients both in the water column and in sediment, making estuaries among the most productive natural habitats in the world. Most existing estuaries formed during the Holocene epoch with the flooding of river-eroded or glacially scoured valleys when the sea level began to rise about 10,000–12,000 years ago. Estuaries are typically classified according to their geomorphological features or to water-circulation patterns. They can have many different names, such as bays, ...

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
