Acnodon Senai
''Acnodon senai'', Sena's pacu, is a species of freshwater ray-finned fish belonging to the family Serrasalmidae, which includes the pacus and piranhas. This fish is found in Brazil. Taxonomy ''Acnodon senai'' was first formally described in 1990 by the ichthyologists Michel Jégu, who is French, and Geraldo M. dos Santos, who is Brazilian, with its type locality given as 0°35'45"S, 52°38'20"W from a beach downstream of Rio Jari, Amapa, Carapatinho Island. This species is classified in the genus ''Acnodon'' which belongs to the subfamily Myleinae in the family Serrasalmidae which is classified in the suborder Characoidei of the order Characiformes. Etymology ''Acnodon senai'' is classified in the genus ''Acnodon'', a name which prefixies ''a-'', meaning without, onto ''knodon'', which means "the projecting teeth on a hunting spear", an allusion to the mistaken perception that the type species of the genus, '' A. oligacanthus'', does not have a spine in front of its do ...

Suborder
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consistent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Acnodon Oligacanthus
''Acnodon oligacanthus'', the slender pacu, is a species of freshwater ray-finned fish belonging to the family Serrasalmidae, which includes the pacus and piranhas. This fish is found in South America. Taxonomy ''Acnodon oligacanthus'' was first formally described as ''Myleus oligacanthus'' in 1844 by the German zoologists Johannes Peter Müller and Franz Hermann Troschel with its type loacliaty given as Suriname. In 1903 Carl H. Eigenmann propsed the new monospecific genus ''Acnodon'' with ''M. oligacanthus'' designated as its type species. ''Acnodon'' belongs to the subfamily Myleinae in the family Serrasalmidae which is classified in the suborder Characoidei of the order Characiformes. Etymology ''Acnodon oligacanthus'' is the type species of the genus ''Acnodon'', a name which prefixies ''a-'', meaning without, onto ''knodon'', which means "the projecting teeth on a hunting spear", an allusion to the mistaken perception that this species does not have a spine in front of i ...

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...
