Hemiodontidae
The Hemiodontidae are a small family (biology), family of freshwater Characidae, characins found in northern South America, south to the Paraná River, Paraná-Paraguay River, Paraguay Basin. The larger species are popular food fish. Hemiodontids have a streamlined body shape; many are fast-swimming, and are able to leap out of the water to escape predators. The adults of all species except ''Micromischodus sugillatus'' have no teeth on their lower jaws. Most species have a round spot on the side of the midbody and a stripe along the lower lobe of the caudal fin. The largest hemiodontids are around in length. Fossil remains of ''Hemiodus'' are known from the Middle Miocene-aged Pebas Formation of Peru. Genera The family has around 29 known species, as well as several undescribed species, in five genus, genera: *''Anodus'' Georges Cuvier, Cuvier, 1829 *''Argonectes'' James Erwin Böhlke, Böhlke & George S. Myers, Myers, 1956 *''Bivibranchia'' Carl H. Eigenmann, Eigenmann, 1912 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemiodus
''Hemiodus'' is a genus of halftooths from South America with the greatest species richness in the Amazon Basin, but also found in the Orinoco, Essequibo, Paraná–Paraguay and Parnaíba River basins.

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] |
Characidae
Characidae, the characids, is a family of freshwater subtropical and tropical fish belonging to the order Characiformes. They are found throughout much of Central and South America, including such major waterways as the Amazon and Orinoco Rivers.Nelson (2006) These fish vary in length; many are less than . The name " characins" is a historical one, but scientists today tend to prefer "characids" to reflect their status as a, by and large, monophyletic group (at family rank). This family includes some of the first characiforms to be described to science, such as '' Charax'' and '' Tetragonopterus'', and thus lend their name to the order, as well as to common names such as "characin" and " tetra". Past taxonomic treatments had a much more expansive definition of the family, including numerous South American fish families such as the piranhas and dorados, as well as the African alestids. Following multiple taxonomic revisions, this was eventually restricted to just the Americ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
