Moxostoma Ugidatli
The sicklefin redhorse (''Moxostoma ugidatli''), is a species of freshwater Actinopterygii, ray-finned fish in the genus ''Moxostoma''. It is Endemism, endemic to the southeastern United States, where it is known from a small section of the Appalachian Mountains in southwestern North Carolina and northern Georgia (U.S. state), Georgia. Long known to the Cherokee people, it was only scientifically recognized as a distinct species in 1992, and only officially given a scientific name in 2025. The fish was once an important food source to the Eastern Band of Cherokee Indians before it nearly disappeared in the 1970s and 1980s. A number of groups and agencies are attempting to preserve the fish, including the N.C. Wildlife Resources Commission, Duke Energy, the Tennessee Valley Authority, the Eastern Band of Cherokee Indians, the Georgia Department of Natural Resources, and the U.S. Fish and Wildlife Service. Taxonomy Etymology According to various sources it is called ugidatli ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class (biology), class of Osteichthyes, bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fish fin, fins made of webbings of skin supported by radially extended thin bony spine (zoology), spines called ''lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister taxon, sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation (anatomy), articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they domi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
