Cocoon fish lungfish that can live in dry soil, and without any water.

if catfish can survive in mud, with very little water content. This fish called Lungfish is even more powerful. With his miraculous ability he will form a similar cocoon until he can live even without water for months or even years. Best friends, incidence, is it true and how do the magical fish Lungfish survive in the arid and arid dry land that has hardened like a rock?

Quoting from AMIA calva via predatoryfishkeepers.com, the lungfish fish also known as the lung fish come from the family species Ceratodontidae and Lepidosirenidae, native habitat in the inland rivers of Africa, Australia and South America. But their population level is very rarely found until it is declared as one of the rare fish species that are approaching extinction.

The shape is quite large can reach a size of 150 cm or 1 meter more like a salamander fish, has small feet in the tail and two hands beside the snout. This ancient fish is very long, it can reach more than 100 years. One example is a Lungfish named Granddad or grandfather, owned by the Shedd Aquarium in Chigago.

Granddad is known to be over 90 years old, but he was forced to end his life by injecting euthanasia to death, because Granddad suffered from health problems. He didn't want to touch food at all, and his health conditions were getting worse. Inevitably the process of euthanasia must be done rather than suffer longer lives.
Lungfish breathe with gills / organs that are very similar to the lungs, more precisely a single primitive lung and do not need to rise to the surface of the water to get oxygen. When he is in a normal living condition in water he will use the gills.

Picture of Lungfish Australia, its body size can reach 1.5 meters more.

But when forced to live in extreme conditions of minimal water, lungfish will change its respiratory system by using suprabranchial organs (single lungs), which is a space divider in the upper part of the gills so that it can swallow air directly in low oxygen levels.

The most powerful species of Lungfish to survive come from African species. During the dry season, the African Lungfish will dig mud with its mouth for the hole where it is lodged. Then he will cover the opening of the hole by producing waterproof dry mucus so that his body is completely wrapped in mud like a butterfly cocoon.

Furthermore, he will carry out the hibernation process, aka long sleep for months to years, to ensure the surrounding soil conditions return to normal watering. Likewise when he is breeding, female Lungfish will collect the remnants of processed fat from snails, worms, small fish and plants in the cocoon's house. Together with the male alias husband, they will make a long tunnel from the mud to place the female to put her eggs.

Until their child's eggs hatch, during this time the female Lungfish will stay with them. While their beloved father guarded the entrance of the mud tunnel so that they would not be attacked by other predatory animals.

So the survival ability of Lungfish is amazing, even though for years without water and food at all, the Lungfish will still be alive during its cocoon nest where it moisturizes the body not to be destroyed or destroyed even though the surrounding soil is dry and hardened. Magical and extraordinary.
