Cave fish

species of fish

The Amblyopsidae are a fish family commonly referred to as cavefish, blindfish, or swampfish. They are small freshwater fish found in the dark environments of caves (underground lakes, pools, rivers and streams), springs and swamps in the eastern half of the United States. Like other troglobites, most amblyopsids exhibit adaptations to these dark environments, including the lack of functional eyes and the absence of pigmentation. More than 200 species of cavefishes are known, but only six of these are in the family Amblyopsidae. One of these, Forbesichthys agassizii, spends time both undergrou

Sinocyclocheilus is a genus of freshwater cyprinid fish endemic to the karst landscapes of southwestern China, predominantly in the provinces of Guizhou, Yunnan, and the Guangxi Zhuang Autonomous Region. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes (some are completely blind). Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back (above the forehead), the function of which is unclear. In contrast, the non-cave or surf

Amblyopsis is a genus of small (up to long) fish in the family Amblyopsidae that are endemic to the central and eastern United States. Like other cavefish, they lack pigmentation and are blind. The most recently described species was in 2014. Uniquely among fish, Amblyopsis brood their eggs in the gill chambers (somewhat like mouthbrooders). It was formerly incorrectly speculated that the same brooding behavior existed in other genera in the family and in the pirate perch (Aphredoderus sayanus). During the Pleistocene period, the modern Ohio river was a barrier of dispersal and created a great
