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 ...

Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used ...

Thyamis
The Thyamis ( el, Θύαμις), also known as Glykys (Γλυκύς) or Kalamas (Καλαμάς), is a river in the Epirus region of Greece. It flows into the Ionian Sea. It is long, and its drainage area is about , over 99% of which on Greek territory. The names of the Chameria region (''Tsamouria'' in Greek), as well as the Chams, derive from the river's name. Thyamis in ancient Greece was mentioned by Pausanias as forming the boundary between Thesprotis and Kestrine. In addition, Suda and Ptolemaeus mentioned it. Some Renaissance scholars believed that the English River Thames owed its name to the River Thyamis, as early Celtic tribes were thought to have migrated from the Epirus region to England. While this belief influenced the modern spelling of the English river's name, it is no longer regarded as credible. Geography The source of the river is near the village Kalpaki, in the northwestern part of the Ioannina regional unit. It flows south at first, and turns ...

Acheron
The Acheron (; grc, Ἀχέρων ''Acheron'' or Ἀχερούσιος ''Acherousios''; ell, Αχέροντας ''Acherontas'') is a river located in the Epirus region of northwest Greece. It is long, and its drainage area is . Its source is near the village Zotiko, in the southwestern part of the Ioannina regional unit, and it flows into the Ionian Sea in Ammoudia, near Parga. The Acheron also features prominently in Greek mythology, where it is often depicted as the entrance to the Greek Underworld where souls must be ferried across by Charon (although some later sources, such as Roman poets, assign this role to the river Styx). Mythology Ancient Greek mythology saw the Acheron, sometimes known as the "river of woe", as one of the five rivers of the Greek underworld. The name is of uncertain etymology. Most classical accounts, including Pausanias (10.28) and later Dante's ''Inferno'' (3.78), portray the Acheron as the entrance to the Underworld and depict Charon fe ...

Louros (river)
The Louros ( el, Λούρος) is a river in the Epirus (region), Epirus region, in northwestern Greece. It is long, and its drainage area is . It emerges from the ground in a large spring located immediately north of the village of Agios Dimitrios, Ioannina, Vouliasta, in Ioannina (regional unit), Ioannina regional unit. It flows south through a canyon, and then a dam followed by a hydroelectric power station. The Louros flows past town of Filippiada, forming the boundary between Arta (regional unit), Arta regional unit and Preveza (regional unit), Preveza regional unit. The river then veers east into the Preveza regional unit, flowing through the municipality of Louros, named after the river. The Louros then empties into the marshes at the northern end of the Ambracian Gulf. With Strymon river, Louros is one of only two rivers in the world where the critically endangered Greek lamprey (''Caspiomyzon hellenicus'') has been found. References Epirus Rivers of Greece L ...

Arachthos (river)
The Arachthos ( el, Άραχθος) is a river in eastern Epirus, Greece. Its source is in the Pindus mountains, near the town Metsovo ( Ioannina regional unit). It is long, and its drainage area is . Its upper course is known as '' Metsovitikos''. From its confluence with the Dipotamos near the village of Batza it is called Arachthos. It flows towards the south, passing between the Athamanika and the Xerovouni mountains. In this place meets the Plaka Bridge, the largest one-arch stone bridge in Greece. It enters the large Pournari Reservoir, in the Arta regional unit, which is about 18 km² and prevents flooding of the city of Arta and also supplies water to most of Epirus. The town of Peta is situated near the dam.

Squalius
''Squalius'' is a genus of fish in the family Cyprinidae found in Europe and Asia. Hybridization is not rare in the Cyprinidae, including this genus. '' S. alburnoides'' is known to be of ancient hybrid origin, with the paternal lineage deriving from a prehistoric species related to ''Anaecypris''; the latter mated with ancestral '' S. pyrenaicus''. Present-day ''S. alburnoides'' mates with sympatric congeners of other species.Collares-Pereira, M.J. & Coelho, M.M.

Fish Described In 1939
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 fi ...
