The Fish That Can Walk Up Waterfalls
The little-known Cryptotora thamicola cavefish, found in Thailand, is just a few inches long and totally blind. But it can do something not only that no other fish can do, but also something that has upended some of our most basic assumptions about evolution and life on this planet: it can walk.

The pelvis and vertebral column of this fish allow it to support its body weight against gravity and provide large sites for muscle attachment for walking.”
