That’s what scientists found out in their detailed study of the skeletons of the hillstream loach fish family in Asia. This fish family includes Cryptotora thamicola, or the cave angel fish (which is also known as the waterfall climbing cave fish). Scientists also found out that 10 other species probably have the ability to walk as well.
By identifying which species of hillstream loaches can potentially go for a wander on terra firma (ignoring the breathing difficulties for a moment), the researchers hope to learn more about how the very first land-walking vertebrates might have made their way out of the water and onto land.
