Tylognathus steinitziorum : ウィキペディア英語版 | Hemigrammocapoeta nana
''Hemigrammocapoeta nana'' is a ray-finned fish species in the family Cyprinidae. It is found in Israel, Jordan, and Syria.〔Goren (2006)〕 Its natural habitats are freshwater rivers, lakes and ponds of the Barada and Jordan River drainage basins, as well as the Kishon River. This bottom-dwelling fish is often overlooked, as it is small and prefers to hide among stones and water plants. It is an omnivore which feeds on aufwuchs.〔 It is threatened by habitat loss, particularly due to water pollution and unsustainable water extraction for agriculture. Droughts perhaps exacerbated by climate change and invasive species also pose problems. Though the populations in lakes are generally holding their own, most of these are small and susceptibl to catastrophic fish kills. The river populations, on the other hand, are declining. Therefore, this species is classified as Vulnerable by the IUCN.〔 ==Footnotes==
