What is the devils holes?
The Devils Pupfish is endangered species of fish from the desert in Nevada. Pupfish is generally desert fish and adapts to live in an extreme environment of American Southwest and Mexico, but The Devils Hole Budfish is a particularly remarkable example of this group of fish. These fish have adapted to live in the water of Fahrenheit (33 degrees Celsius) from Devils Hole, a geothermal pool in the Amargosa desert. Devils Hole was originally known as "Minera's bath" and later became a "devilish hole", but at the beginning of the 20th century "Devils Hole" began to appear as an alternative spelling on some government documents. In the end, the officials retreated to the inevitable and officially entitled Spring "Devil's Hole", a lot to dismay regional grammar.
These fish are relatively small, around the size of the bowel and during the period of reproduction they become an electric blue color, with striking black stripes along the back. In the type of body, the hole of the devils is very similar to other Pupins, with a large head anddistinctive anal fins. They feed on diatoms, which are naturally present in the pool, breeding and feeding the limestone shelf just below the surface of the devil hole.
In 1890, people first noticed the devil's holes; These fish were identified as a unique species at the age of 30, when about 500 individuals were counted. In the 1960s, scientists acknowledged that the population of fish was declining, and a step was taken to protect the package under the Act on Endangered Species. It turned out that it was questionable because the need to reduce irrigation to protect the fish that disintegrated into the profits of neighboring agricultural fears. The successful judicial case paved the way for similar moves to protect the ennamed species across the country and the population began to stabilize.
By 2006, however, fish populations rejected less than 50 individuals for no apparent reason. Some individuals have been moved to a new environment in an effort to preserve the species but a sudden declineThe original population after the movements were made to protect themselves, was a mysterious and source of concern. Some scientists have suggested that the cheap hole is very sensitive to changes in their environment, so that the reduction number of fish could be responsible for a gentle shift in water, temperature or chemistry levels. Scientists are also confused about how fish have got into a devil's hole because it is not associated with any known water formations.
