What the hell is a desert fish?

Many people think, "how can there be fish in a desert where there is drought and lack of water? however, there is indeed a species of desert fish known as desert fish. Desert fish is a relatively small fish of the family Carpiodonidae, which lives in the" death Valley "of dead swamps. This is still the lowest, driest and hottest area in North America. Let's take a look at what desert fish are.

What the hell is a desert fish?

Desert fish is an endangered species that lives in the "death Valley" of dead marshes. A rare source of water in the desert is a necessary condition for its survival. All species live in a small pool in the death Valley, but are on the verge of extinction because of the depletion of groundwater resources. However, the behavior of desert fish depends on the environment of its habitat, and over-reliance on the only habitat will make the desert fish in the devil's hole easy to extinct. For this reason, three shelters were built to mimic the devil's cave environment. Five years later, it was found that the phenotype of desert fish in the shelter was very different from that in the devil's cave.

Where do desert fish live?

The Devil's Cave, 96km east of death Valley, is the only natural habitat for desert fish. Geographers estimate that the hole is at least 130m deep and has been around for 500000 years. Probably because of an earthquake 50, 000 years ago, the top of the cave collapsed, exposing it and the water inside. The water in the Devil's Cave is lack of oxygen, and the temperature remains 33.3-33.9 ℃, which is the upper limit that most fish can tolerate.

Where did the desert fish come from?

The body shape, brain and behavior of desert fish are very flexible, and their development is greatly affected by the early environment. This flexibility is called phenotypic plasticity and plays a key role in the formation of phenotypic diversity of desert fish. Many animals, such as bees and vertebrates, have surface plasticity. The formation of some special phenotypes depends on their special habitat. Once the habitat changes, the phenotypic characteristics will also change. Plasticity also has a genetic basis, which is determined by the individual genome and living environment. A new direction of adaptive evolution depends on the variability of the organism itself, which depends on the phenotypic plasticity of genotype and structure, physiology and behavior.
