Valencia letourneuxi, the Corfu toothcarp, is a species of fish in the family Valenciidae. It is found in Albania and Greece. Its natural habitats are rivers, freshwater marshes, freshwater spring, and coastal saline lagoons. It is threatened by habitat loss. The specific name of this fish honours the collector of the type, the botanist Aristide-Horace Letourneux (1820-1890). The species was described as Fundulus letourneuxi in 1880 by Henri Émile Sauvage with a type locality of Cressida, Corfu. It also formerly occurred on the island of Lefkas but is now considered to be extirpated from both there and Corfu. Valencia letourneuxi is a highly endangered freshwater species that faces threats from habitat degradation, water abstraction, and foreign species. While little is known of its ecological history, V. Letourneuxi produce 2.2 mm eggs during the spring on aquatic plants in stagnant water that has a lot of vegetation.

Oxynoemacheilus hamwii, the Orontes sportive loach, is a species of ray-finned fish in the genus Oxynoemacheilus. This species is found in the headwaters of the Orontes River but is now restricted to three streams in the Turkish part of the drainage, two joining the lower Orontes in Turket and the third flowing into the Afrin River in Syria, and has been extirpated from Syria. It was described as being very common in the late 20th century, but it is sensitive to pollution and requires clear, flowing streams over mud or gravel. The drainage of the Orontes is heavily used by humans and lower rainfall in the region caused by climate change may exacerbate the threat to this species by increasing the amount of water taken from the streams by humans and by lowering the water table.
Enteromius collarti is a species of ray-finned fish in the genus Enteromius which is only found in Angola.
Osteobrama feae is a species of ray-finned fish in the genus Osteobrama which is found in the Indian state of Manipur and in Myanmar, being common throughout its range.
