The lung fish fish time forgot

The lung fish fish time forgot Lung fish, old fish that are found in Australia, South - America and Africa. The lung group contains only a few species of fish and no more than six species are known. These six types can be divided into two different families. A family, Lepidosirenidae, five species in the South - America and Africa. The other family is Ceratodidae display contains only one species, the Australian lung fish. All fish in the lung by a joint body that gave them their names. They have developed the lung, the survival in water, with very low levels of oxygen, where other fish can not survive. The lungs may also, in order to survive out of water. The lungs in the lung fish are very similar to the lung in primitive reptiles. Lung fish has been given to the Lower Devonian field, this means that they were more than 100 million years ago. The number of species used to be much more numerous in the past, but all six species are now extinct. Lung fish are easy to see how they look. Snakelike are searching primitive organisms. All species of fish can grow lung very large and the African Lung fish can grow to more than 2 m / 6 m in length. Are very species of predators that eat or try to eat everything in his big mouth. (Includes aquarium decoration and heating), their natural diet consists of fish, shrimps, crabs and other devices. The family of Lepidosirenidae lung fish can survive in a little water and the African Lung fish can survive without water for up to two years. South America lung water fish survive low - level, digging a hole in the bottom mud, where their nests. They wait in the nest until the water retus. Africa is a better fish Lung survivor. There shall be no support for building a nest, but also for their bodies secretion. This secretion is a cocoon, like leather, which helps the lungs moist until the fish retus to water. They hibeate during the wait time for new water and can be regarded as already mentioned, trying to survive in the desert, like for two years or maybe more. The Australian lung fish do not hibeate like some other lungfishes. This makes them dependent on water, but to survive and find water in very small. All species of fish Lepidosirenidae lung builds a sort of nest in which to deposit their eggs. The male guards the eggs until they hatch. The Australian lung fish does not build any nest. Just deposit the eggs on the ground in their habitat.
