Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Pseudobatos
''Pseudobatos'' is a genus of fish in the Rhinobatidae family. Although its constituent species were previously assigned to ''Rhinobatos'', recent authors treat it as distinct. They are found in warmer coastal parts of the Americas, ranging from northern Chile to California (USA) on the Pacific side, and from northeastern Argentina to North Carolina (USA) on the Atlantic side. They are brownish or grayish above, and reach up to depending on the exact species. Species There are nine currently recognized species in this genus: * ''Pseudobatos buthi'' K.M. Rutledge, 2019 (Spadenose guitarfish) * ''Pseudobatos glaucostigmus'' ( D. S. Jordan & C. H. Gilbert, 1883) (Speckled guitarfish) * ''Pseudobatos horkelii'' ( J. P. Müller & Henle, 1841) (Brazilian guitarfish) * ''Pseudobatos lentiginosus'' (Garman, 1880) (Atlantic guitarfish) * ''Pseudobatos leucorhynchus'' ( Günther, 1867) (Whitesnout guitarfish) * '' Pseudobatos percellens'' (Walbaum, 1792) (Chola guitarfish) * ''Pseudoba ...
