Nice feet, where's the lungs? I catch plenty of catfish. they can live a long time out of water. just because a fish flips itself across short bits of land and go into other ponds doesn't mean it's evolving. In fact there is not even a hint of anyhing 'evolving' on that fih, whaich has been observed for hundreds of years.
Or like a crayfish, some live in creeks others dig holes in a pasture, but they are all still crayfish, or other crustaceans some in water some on land, still a crustacean.

Don't like the walking catfish, do a little reading on the northern snakehead.
can live for a few days out of water, can crawl between water sources.
don't know if it has lungs or not, but it is an interesting phenomenon regardless.
Clarias batrachus (walking catfish) has a primitive sac structure within the gills that allow it to obtain atmospheric oxygen.
