Limia Islai
''Limia islai'', also known as the tiger limia, is a species of fish within the family Poeciliidae. This species is one of several ''Limia'' that are endemic to Lake Miragoâne, Haiti. Description ''Limia islai'' can be distinguished by almost all other ''Limia'' species by the presence of black vertical stripes across the fishes body. The only other ''Limia'' species to possess a similar striping is '' Limia nigrofasciata.'' Stripes are present on both male and female members of ''L. islai''. The number of stripes on an individual fish can vary between 4 and 12. ''Limia islai'' have slender bodies which are olive green in colour and fish possess yellow pigment in their snout and fins. Distribution and habitat ''Limia islai'' is endemic to Haiti, where the species is restricted to the Tiburon Peninsula of Southwest Haiti. This species has only been recorded in the coastal Lake Miragoâne. The lake is freshwater and reaches a maximum depth of 45 meters. The habitat consists o ...

Poeciliidae
The Poeciliidae are a family of freshwater fishes of the order Cyprinodontiformes, the tooth-carps, and include well-known live-bearing aquarium fish, such as the guppy, molly, platy, and swordtail. The original distribution of the family was the Southeastern United States to north of Río de la Plata, Argentina, and Africa, including Madagascar. Due to release of aquarium specimens and the widespread use of species of the genera ''Poecilia'' and '' Gambusia'' for mosquito control, though, poeciliids can today be found in all tropical and subtropical areas of the world. In addition, ''Poecilia'' and ''Gambusia'' specimens have been identified in hot springs pools as far north as Banff, Alberta. Live-bearing Although the whole family Poeciliidae is known as "live bearers" ( viviparous), some species are egg-scattering with external fertilization. All African species are egg-layers, and (with the exception of the members of the genus '' Tomeurus''), all American species ar ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List ...

Limia
''Limia'' is a genus of livebearing fishes belonging to the Cyprinodontiform family Poeciliidae, which includes other livebearers such as platys, swordtails (genus ''Xiphophorous''), guppies and mollies (genus ''Poecilia''). They are found in fresh and brackish water. Of the 21 described ''Limia'' species, 17 are endemic to Hispaniola, one is found on both Hispaniola and Jamaica, and the Cayman Islands, Cuba, and Venezuela have an endemic species each. Limia are popular in aquaria among more advanced hobbyists. Origin and evolution Two schools of thought on the origin of the genus exist. The first suggests that Limia arose from colonization by a seawater-tolerant species that crossed over shallow waters from the North or South American mainland. The strongest evidence for this model is that of the approximately 60 species of freshwater fish in the Antilles, all of them are secondary division freshwater fish. This indicates the ancestors of all fish present on the islands a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Miragoâne
Lake Miragoâne (french: Étang de Miragoâne) is a lake in Haiti, located one kilometer southeast of the city of Miragoâne. It is one of the largest natural freshwater lakes in the Caribbean. The lake is 12 km (7.5 mi) long and 25 km² (9.7 mi²) in area. Fauna Many species of water bird inhabit Lake Miragoâne including the snowy egret (''Egretta thula),'' the West Indian whistling duck (''Dendrocygna arborea''), the yellow-crowned night heron (''Nyctanassa violacea)'' and the glossy ibis (''Plegadis falcinellus''). Lake Miragoâne is also considered an important centre of endemism for the livebearing genus ''Limia ''Limia'' is a genus of livebearing fishes belonging to the Cyprinodontiform family Poeciliidae, which includes other livebearers such as platys, swordtails (genus ''Xiphophorous''), guppies and mollies (genus ''Poecilia'').

Humpbacked Limia
The humpbacked limia or black-barred limia (''Limia nigrofasciata'') is a critically endangered species of poeciliid fish which is endemic to Haiti. Its common name is derived from the hump males develop as they age. It is sometimes kept in home Aquarium, aquaria. Description ''Limia nigrofasciata'' grows to a length of in standard length. Both males and females are colorful, with translucent and glittery bodies featuring dark vertical bars (from which the specific epithet ''nigrofasciata'' is derived). The males also have an enlarged dorsal fin with purple flecks. As they mature, the males become distinctly humpbacked and their golden base color intensifies. Ecology ''Limia nigrofasciata'' exclusively inhabits Lake Miragoâne, but it is not particular about the type of substrate (marine biology), substrate. The fish are notably social and usually form large Shoaling and schooling, schools. In habitats characterized by submerged aquatic vegetation and muddy bottoms, ''Limia nig ...

Tiburon Peninsula
The Tiburon Peninsula (french: Péninsule de Tiburon), or The Xaragua Peninsula, simply "the Tiburon" (''le Tiburon''), is a region of Haiti encompassing most of Haiti's southern coast. It starts roughly at the southernmost point of the Haiti-Dominican Republic border and extends westward near Cuba, forming a large headland. Three of Haiti's ten departments are located entirely within the region. They are the departments of Grand'Anse, Nippes and Sud. Etymology The wordTiburonand Xaragua are linked to the Taino natives who were the region's first inhabitants. The region is often referred to as the Great South, le Grand-Sud (french), or Nansid (Haitian). Administrative Division The Tiburon is 1 of the 4 regions of Haiti, administrated through 4 departments and 1 arrondissement. Half of Sud-Est is also located within the Tiburon Peninsula. A large part of Ouest department is also located in the region, with the capital, Port-au-Prince serving as the line of demarcation betw ...

Courtship Display
A courtship display is a set of display behaviors in which an animal, usually a male, attempts to attract a mate; the mate exercises choice, so sexual selection acts on the display. These behaviors often include ritualized movement ("dances"), vocalizations, mechanical sound production, or displays of beauty, strength, or agonistic ability. Male display In some species, males will perform ritualized movements to attract females. The male six-plumed bird-of-paradise ( ''Parotia lawesii'') exemplifies male courtship display with its ritualized "ballerina dance" and unique occipital and breast feathers that serve to stimulate the female visual system. In ''Drosophila subobscura,'' male courtship display is seen through the male's intricate wing scissoring patterns and rapid sidestepping. These stimulations, along with many other factors, result in subsequent copulation or rejection. In other species, males may exhibit courtship displays that serve as both visual and auditory sti ...

Gonopodium
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 to lure ...

Livebearers
Livebearers are aquarium fish that retain the eggs inside the body and give birth to live, free-swimming young. Among aquarium fish, livebearers are nearly all members of the family Poeciliidae and include guppies, mollies, platies and swordtails. The advantages of livebearing to the aquarist are that the newborn juvenile fish are larger than newly-hatched fry, have a lower chance of mortality and are easier to care for. Unusual livebearers include seahorses and pipefish, where the males care for the young, and certain cichlids that are mouthbrooders, with the parent incubating the eggs in the buccal cavity. Common aquarium livebearers Species of interest to aquarists are almost always members of the family Poeciliidae, most commonly guppies, mollies, platies, swordtails, Endler's livebearer, and mosquito fish. Most of these are ovoviviparous, with the developing embryos receiving no nourishment from the parent fish, but a few are viviparous, receiving food from the maternal blo ...
