Latest Amblyopsidae Stories
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.
Do animals that have evolved for millions of years underground, completely isolated from the day-night cycle, still "know" what time it is?
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.
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 Alabama cavefish, Speoplatyrhinus poulsoni, is a critically endangered type of cavefish which lives in underground pools in Key Cave, located in northwestern Alabama on the Key Cave National Wildlife Refuge. This is the only known location of the fish, and was discovered in 1974 by Cooper and Kuehne. Only nine specimens of the cavefish have been observed and scientists estimate that less than 100 of the fish are left on the planet. It is believed that this fish is the rarest of...
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...
