The Gonostomatidae are a family of mesopelagic marine fish, commonly named bristlemouths, lightfishes, or anglemouths. It is a relatively small family, containing only eight known genera and 32 species. However, bristlemouths make up for their lack of diversity with numbers: Cyclothone, with 12 species, is thought to be the most abundant vertebrate genus in the world, numbering in the hundreds of trillions to quadrillions.
Fundulus is a genus of ray-finned fishes in the superfamily Funduloidea, family Fundulidae.

Typhlogarra widdowsoni, the Iraq blind barb or Haditha cave garra, is a species of cyprinid fish endemic to underground water systems near Haditha in Iraq. It is the only species in its genus. This cavefish is considered critically endangered because of water extraction, which has lowered the groundwater level. Once abundant, a survey in 2012 found that it now was very rare. Another species from the same place, Caecocypris basimi, may already be extinct. The only other known cavefish in Iraq is Eidinemacheilus proudlovei.

It is a pelagic species that comes to shore in spring–early summer to spawn. It is threatened by the falling water levels of Lake Hazar due to water abstraction and reduced rainfall due to climate change.
The Valencia hispanica or Valencia toothcarp is a species of freshwater fish in the Valenciidae family endemic to the south of Catalonia and the Valencian Community, Spain.

The Sakarya toothcarp is a species of freshwater fish in the family Cyprinodontidae. It is endemic to the upper Sakarya River basin in Turkey. It is threatened by water abstraction, damming and a reduction of rainfall due to climate change. The specific name honours the German zoologist Wolfgang Villwock (1930-2014) of the University of Hamburg.
