Poecilocharax Callipterus
''Poecilocharax callipterus'' is a species of fish named after its elongated dorsal fins and anal fins. ''P. callipterus'' is the first species of crenuchinae discovered after a gap of 57 years.. '' Poecilocharax rhizophilus'' was also discovered moments later. Description ''Poecilocharax callipterus'' lives in the Apuí region of Brazil Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area .... The species is around 3 centimeters long and has a mixture of red long fins, and a black spot on its tail. ''P. callipterus'' has also been found with vibrant orange coloration.

Fish
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 arthrop ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans ( whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species 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 large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against r ...

Fish Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

Crenuchidae
The Crenuchidae, South American darters, are a family of freshwater fish of the order Characiformes. The 12 genera include about 74 species, though several species are undescribed. These fish are relatively small (usually under in standard length) and originate from eastern Panama and South America. Both subfamilies were previously included in the family Characidae, and were placed in a separate family by Buckup, 1998. Buckup, 1993, revised all genera, except ''Characidium''.Buckup, P.A. 1993.

Apuí
Apuí is a municipality located in the Brazilian state of Amazonas. Its population was 22,359 (2020) and its area is 54,240 km2. Gold rush The municipality shot to fame in December 2006, when a Brazilian maths teacher by the name of Ivani Valentim da Silva posted descriptions of miners scooping up thousands of dollars in gold in the area. In just three months, between 3,000 and 10,000 people poured into the area, cutting down trees, diverting streams and digging wildcat mines. The city was nicknamed ''Eldorado do Juma'' after the mythical El Dorado. Conservation The municipality contains 92% of the Apuí Mosaic, a jointly-managed collection of conservation units. It contains the Sucunduri State Park, created in 2005. It also contains the Sucunduri State Forest, a sustainable use conservation unit created in 2005. It contains 72% of the Guariba Extractive Reserve, also created in 2005. It also contains the Bararati Sustainable Development Reserve, created at the same ti ...
