Curimatidae
The Curimatidae, toothless characins, are a family of freshwater fishes, of the order Characiformes. They originate from southern Costa Rica to northern Argentina. The family has around 105 species, many of them frequently exploited for human consumption. They are closely related to the Prochilodontidae. This family lacks jaw teeth, although they do sometimes have small teeth on their pharyngeal plates. They eat films of slime coating underwater surfaces, which consist largely of algae, zooplankton and detritus. It has been suggested that feeding behavior of some species like '' Psectrogaster essequibensis'' may change its diet pattern in function of the sediment content of the water, showing a regime mainly based on algae in waters with high sediment load, until an omnivorous or detritivore regime in waters with low sediment load. Classification The family has eight genera and around 105 species: Family Curimatidae * '' Curimata'' (13 species) * '' Curimatella'' (five speci ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilateral symmetry, bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and th ...

Taxa Named By Rosa Smith Eigenmann
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
