The Lung Fish

The lung fish is one of the oldest forms of evolution that we have on this planet, this fish has small legs on the back of it, but also can walk on land and breath our air. There are a few of these fish such as the snake head fish and the Giant Snake head Fish that have the same abilities. But the lung fish is one of the oldest known to man, and it has its own abilities.

The Lung Fish

These fish used to be known world wide and are also known as the salamander fish. You will only find these fish in Africa, South America and Australia. These fish have not changed much from the fossils found of such fish from millions of years ago. These were one of the first fish to leave the water. They are a fresh water fish these days, while back in the years of when the fossil was found, they appeared to be salt water. This is the only real change that you could see just by looking at their behaviour. They have evolved internally rather than externally. They have got the ability to breath our air, but they also have the ability to kill themselves and bring them selves back to life.

They can stay in a dead like state for up to three years, and just reamerge from where ever they have hid for this time. Usually in Africa when the rivers dry up they burry them selves in the mud and go into a coma like state and can stay there for up to three years. There have been builders in Africa that have been using the mud as house building materials. They found out that when the monsoon weather arrives these fish wake up and just break out of the walls and simply walk themselves back to the river with their small legs and their adapted fins they have that help them walk. When they are on land these fins act like legs and when they reach the water they use them as a normal fish would use their fins.

The lung fish is the only fish that have lungs this is what enables it to breath on land, these paired lungs connect to a pharyx like ours do. Other fish have a single lung feature that is nown as a swim bladder and is located behind its brain, the gills of a normal fish regulate the oxygen from the water.

    I love reading your science stuff. You’re like my very own, living, breathing, walking, talking NatGeo. You make great scientific contributions for learning new things.

    That must be quite a shock to have a piece of your wall wake up and go walking off into the rain! Good article.

    This is truly amazing the way they can be in a death-like state for up to 3 years! Very interesting!

    Very strange fish. Wonder how it gets oxygen while in the death-state of being in a dried-up river? Fish probably ages still, but I’m thinking long distance space flights… if astronauts could do something like this (well, the would not be ‘human’ anymore of course!) but whatever powers this longevity might have some useful application for the space program…

    kewl read!
