Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actino ...

Rasbora
''Rasbora'' is a genus of fish in the family Cyprinidae. They are native to freshwater habitats in South and specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to long, although most species do not surpass and many have a dark horizontal stripe. Several species are regularly kept in aquariums. As a common English name, "rasbora" is used for many species in the genus ''Rasbora'', as well as several species in genera '' Brevibora'', '' Boraras'', ''Megarasbora'', '' Metzia'', '' Microdevario'', '' Microrasbora'', ''Rasboroides'', ''Rasbosoma'', '' Sawbwa'', ''Trigonopoma'' and '' Trigonostigma''. Some of these related genera were included in the genus ''Rasbora'' in the past. In a 2007 analysis, ''Rasbora'' was found to not be a monophyletic assemblage. However ''Boraras'' and ''Trigonostigma'' were determined to be monophyletic.Mayden, R.L., Tang, K.L., Conway, K.W., Freyhof, J., Chamberlain, S., Haskins, M. ...

Fish Described In 2013
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most ...
