Leptolebias
''Leptolebias'' is a ray-finned fish genus of the killifish family Rivulidae. Like many of their relatives, they are rather ambiguously known as "pearlfish". They are endemic to the coastal areas of Brazil, where they inhabit ephemeral pools in tropical forests like the Mata Atlântica (or what remains thereof) and restinga. Rare and little-known, the entire genus seems to be close to extinction. Specifically, ''Leptolebias'' species have been found in two regions to date: between Maricá and Vila de Cava in Rio de Janeiro state, and between Itanhaém in southern São Paulo state and the Paranaguá bay catchment area in Paraná state. Description These small fishes measure only 2–3 cm (around one inch) in standard length. The females are colored uniformly brown, without darker markings, as are the females of some related killifishes. The males may have some dark pigmentation, but it does not extend into the distal dorsal fin, as it does in many related genera. Otherwis ...

Rivulidae
The Rivulidae are a family of killifishes in the order Cyprinodontiformes. They are commonly known as rivulids, South American killifish or New World killifish. The latter names are slightly misleading, however, as they are neither restricted to South America – though most are in fact found there –, nor are they the only killifishes from the Americas. Occasionally, they are still referred to as rivulines, a term dating back to when they were considered a subfamily of the Aplocheilidae. The subfamilial name "Rivulinae" was already established for noctuid moths by Augustus Radcliffe Grote in 1895. That name, though it is the senior homonym, may be suppressed because the name Rivulinae for the fish subfamily is widespread, whereas the moth taxon is little used. The use of Rivulidae as the name for this family may need to be ruled in by the International Commission on Zoological Nomenclature. The alternative family-group name Cynolebiidae Hoedeman 1961 has been proposed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish Of South America
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Cyprinodontiformes
Cyprinodontiformes is an order (biology), order of Actinopterygii, ray-finned fish, comprising mostly small, freshwater fish. Many popular aquarium fish, such as killifish and Poeciliidae, live-bearers, are included. They are closely related to the Atheriniformes and are occasionally included with them. A colloquial term for the order as a whole is toothcarps, though they are not actually close relatives of the true carps – the latter belong to the superorder Ostariophysi, while the toothcarps are Acanthopterygii. The families of Cyprinodontiformes can be informally divided into three groups based on reproductive strategy: Viviparity, viviparous and Ovoviviparity, ovoviviparous (all species give live birth), and Oviparity, oviparous (all species are egg-laying). The live-bearing groups differ in whether the young are carried to term within (ovoviviparous) or without (viviparous) an enclosing eggshell. Phylogeny, Phylogenetically however, one of the two suborders – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Sprague 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 Society of Ichthyologists and Herpetologists. Myers was also head of the Division of Fishes at the United States National Museum, and held a position as an ichthyologist for the United States Fish and Wildlife Service. He was also an advisor in fisheries and ichthyology to the Brazilian Government. He was a prolific writer of papers and books and is well known to aquarists as the man who first described numerous popular aquarium species such as the flame tetra (''Hyphessobrycon flammeus''), the black-winged hatchetfish (''Carnegiella marthae''), the ram cichlid (''Microgeophagus ramirezi'') and, most notably, the neon tetra. He also erected the genera ''Aphyosemion'' and ''Fundulopanchax'', which include dozens of widely kept killifish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
