Latest Cave fish Stories
Scientists estimate that fewer than 100 Devils Hole pupfish remain in their Mojave Desert home, but a conservation biologist at the University of California, Berkeley, is giving important guidance in the efforts to rescue them by establishing a captive breeding program.
A new eyeless cavefish is described from Indiana and named after the Indiana Hoosiers. It is the first new cavefish species described from the U.S. in 40 years.
A newly-identified genetic association with facial asymmetry in ancient cavefish could shed new light into mysteries surrounding conditions such as cleft palate or hemifacial microsomia in humans.
In a blind fish that dwells in deep, dark Mexican caves, scientists have found evidence for a long-debated mechanism of evolutionary change that is distinct from natural selection of spontaneously arising mutations
Researchers are first to show ancient trans-oceanic relationship for vertebrate cave animals
The blind Mexican cavefish (Astyanax mexicanus) have not only lost their sight but have adapted to perpetual darkness by also losing their pigment (albinism) and having altered sleep patterns.
Cave life is known to favor the evolution of a variety of traits, including blindness and loss of eyes, loss of pigmentation, and changes in metabolism and feeding behavior.
University of Maryland biologists have identified how changes in both behavior and genetics led to the evolution of the Mexican blind cavefish (Astyanax mexicanus) from its sighted, surface-dwelling ancestor.
For the first time, an earthquake was recorded live in Devils Hole, home to the only population of a critically endangered pupfish species.
By Keith Rogers By KEITH ROGERS REVIEW-JOURNAL Tiny neon-blue pupfish that are struggling to survive in a spring- fed cave in Nye County have rebounded this fall to 126 adult fish, 34 more than last fall's count and the highest number recorded since 2004, a federal biologist said Wednesday.
Amblyopsidae is a family that holds six species of cavefish, also known as blindfish or swampfish, that reside in swampy and dark waters in eastern areas of the United States. Although there are over 170 species of cavefish, only six of these are classified in the Amblyopsidae family, some of which reside in swamps, while others reside in the water systems of caves like those in the Mammoth Caves in the state of Kentucky. Some of the most notable of these species include Chologaster cornuta,...
The Devil's Hole pupfish, Cyprinodon diabolis, is an endangered species of fish native to Devil's Hole, a geothermal (92Â°F), aquifer-fed pool within a limestone cavern in the Amargosa Desert of Nevada east of Death Valley. It is the smallest desert pupfish species, averaging .75 in (19 mm) in length. Physical Description Devil's Hole pupfish are less than .98 in (2.5 cm) long and resemble other pupfish in shape. They lack pelvic fins and have large heads and long anal fins. Breeding...
Astyanax jordani is a freshwater fish of the Characin family (family Characidae) of order Characiformes, native to Mexico. It is often referred to by its local Spanish name Sardina Ciega but is more commonly called the Cave tetra. A blind cave fish, A. jordani is a recent evolution from the Mexican tetra (A. mexicanus). While it can be confused with the blind cave form of A. mexicanus, it evolved separately from the surface form, and is considered a different species. (IUCN, however,...
The Northern cavefish or Northern blindfish, Amblyopsis spelea, is found in caves through Kentucky and southern Indiana. It is listed as a threatened species in the United States and the IUCN lists the species as vulnerable. The White River, flowing east to west south of Bedford, Indiana, delimits the northern range of Amblyopsis spelea. These fish are not found in caves north of the White River.
The Ozark cavefish, Amblyopsis rosae, is a small subterranean freshwater fish native to the United States. It has been listed as a threatened species in the United States since 1984; the IUCN lists the species as vulnerable. The Ozark cavefish is pinkish-white and reaches a maximum length of 2 in (5 cm). The head is flattened, and it has a slightly protruding lower jaw. The fish has no pelvic fin; the dorsal and anal fins are farther back than on most fish. The Ozark cavefish has only...
