Erythrinidae
The Erythrinidae are a family of fishes found in rivers and other freshwater habitats from Costa Rica south as far as Argentina. They are common and are caught with hooks by fishermen, partially because of their voracious behaviour. They are sometimes called ''trahiras'' (also spelled trairas) or ''tarariras''. The Erythrinidae include cylindrical fish with blunt heads, and prey on other fish. They can reach lengths up to . Some species can breathe air, enabling them to survive in water low in oxygen, and even to move over land between ponds. The earliest definitive remains of the family are of '' Hoplias'' from the Middle Miocene of Colombia. Potential fossil remains are known from the Early Paleocene-aged Tenejapa-Lacandón Formation of Mexico. The three genera in this family appear to have diverged from one another over the Paleogene. However, most species within the family are relatively young, their evolution influenced by major tectonic changes in South America over the N ...

Paleohoplias
''Paleohoplias'' is an extinct monospecific genus of fish in the family Erythrinidae found in Brazil, South America. The type species ''Paleohoplias assisbrasiliensis'' was described in 2003, and was found in Solimões Formation in the State of Acre, Brazil, dating to Huayqueriense- Montehermoseuse (Late Miocene-Pliocene) age. Etymology The generic name ''Paleohoplias'' is Greek for "palaios" which means old, and "hoplias", which is a closely related genus of fish in the same family Erythrinidae. The species name ''assisbrasiliensis'' is in reference to the city of Assis Brasil, which is near the type locality. Classification ''Paleohoplias'' is one of four genera within the family Erythrinidae, and the only extinct genus. It is most closely related to the genus ''Hoplias ''Hoplias'' is a genus of fish in the family (biology), family Erythrinidae found in Central America, Central and South America.

Characiformes Families
Characiformes is an order of ray-finned fish, comprising the characins and their allies. Grouped in 18 recognized families, more than 2000 different species are described, including the well-known piranha and tetras.; Buckup P.A.: "Relationships of the Characidiinae and phylogeny of characiform fishes (Teleostei: Ostariophysi)", ''Phylogeny and Classification of Neotropical Fishes'', L.R. Malabarba, R.E. Reis, R.P. Vari, Z.M. Lucena, eds. (Porto Alegre: Edipucr) 1998:123-144. Taxonomy The Characiformes form part of a series called the Otophysi within the superorder Ostariophysi. The Otophysi contain three other orders, Cypriniformes, Siluriformes, and Gymnotiformes. The Characiformes form a group known as the Characiphysi with the Siluriformes and Gymnotiformes. The order Characiformes is the sister group to the orders Siluriformes and Gymnotiformes, though this has been debated in light of recent molecular evidence. Originally, the characins were all grouped within a singl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tenejapa-Lacandón Formation
The Tenejapa-Lacandón Formation is a geological formation and lagerstätte in southern Mexico and western Guatemala. It preserves fossils dating to the Early Paleocene. It is located primarily in the Mexican state of Chiapas, but outcrops lie as far west as Petén Department, Petén, Guatemala. Some consider it as two distinct formations, the Tenejapa Formation to the west and the Lacandón Formation to the east, which are contiguous and contemporary with each other. The Lacandón Formation was deposited in a shallow inshore marine habitat, whereas the Tenejapa Formation was deposited in a deep offshore habitat. They appear to preserve a marine ecosystem deposited on the western margin of the Caribbean Sea. The most prominent exposures are at the División del Norte and Belisario Domínguez quarries near Palenque, Chiapas, which contain articulated fish skeletons belonging to a variety of taxa of both Cenozoic and Mesozoic affinities. This formation was also the source of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, studies and deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The Indian elephant (''Elephas maximus'') is an extant species, and the woolly mammoth (''Mammuthus primigenius'') is an extinct species. * The moose (''Alces alces'') is an extant species, and the Irish elk (''Megaloceros giganteus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species (" Lazarus species"), or if previously known extant species ...

Fish Of South America
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Fishes Of The World
''Fishes of the World'' is a standard reference for the systematics of fishes. It was first written in 1976 by the American ichthyologist Joseph S. Nelson (1937–2011). Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science. The book begins with a general overview of ichthyology, although it is not self-contained. After a short section on Chordata and non-fish taxa, the work lists all known fish families in a systematic fashion. Each family is given at least one paragraph, and usually a body outline drawing; large families have subfamilies and tribes described as well. Notable genera and species are mentioned, though the book does generally not deal with the species-level diversity. The complexities of the higher taxa are described succinctly, with many references for difficult points. The book does not contain any color illustrations. The fourth edition was the first to inco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodore Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist, and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington, DC, in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes, and mollusks most particularly, although he maintained proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, DC. Fellow members frequently mocked him for his vanity. He was president of the American Asso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
