Did fish ever walk on land?
by
The earliest fish potentially capable of walking on land is Tiktaalik roseae, a species of sarcopterygian that lived approximately 375 million years ago, during the late Devonian Period, in what is today the Canadian Arctic.
The findings are based on CT scans and a new evolutionary map of the hillstream loach family, which includes the only living fish species caught in the act of walking: a rare, blind cavefish known as Cryptotora thamicola, or the cave angel fish.
Why do fish walk on land?
They have spent so much time out of the water that they’ve adapted how they move, breathe, and see on land.
