What is the cave?

Cave is a number of fish that adapted to life near complete darkness. Because of this environment, the fish lacks color and is often blind. Some varieties have no eyes at all. There are about 32 caves around the world. None was found in caves without entrances. If there is no water to the cave, no fish is able to reach the lake inside. Fish can also live outside the caves. Some live in above -ground swamps and earn them nickname Swampfish

Due to two significant mutations, a cave fisherman is generally easy to identify. First, because they live in a dark environment where vision is limited or impossible, most adult caves have no eyes. Some have small bumps or brands where the eyes were once; However, most adult caves are blind.

Many varieties have eyes when they are first hatched. Like fishing, either atrophy of the eyes or a layer of skin grows to cover them. Some studies have shown that when different varieties of cave are masked, they can produce observed sweatOmky. Scientists believe it works because the genetic mutation that causes blindness in fish is different in each variety. When both mutations mix, they tend to disturb each other.

Without eyes, fish developed another way to feel the world around them. A series of tiny bumps, just like taste buds on human language, cover the skin of fish. These bumps are able to capture temperature, water currents and other things that help the fish navigate.

The second significant mutation is the lack of pigment. This is also due to the darkness of their environment. Most fish use color as camouflage or communicate with other fish. For example, men of the species can be multicolored than women of the same kind. If the look is impossible, these colors make no sense, so the cave does not have skin pigmentation at all. Some seem pinkish because it is possible to see blood vessels through colorless skin.

Some people keep these fishLike pets. Aquarium owners like them because they are active and well with other fish. It is also easy to take care of them because they eat almost any food it provides.
