Study of Asia’s hillstream loaches reveals keys to fish family’s land-walking abilities

A new genetic and morphological study of South Asia’s hillstream loach (Balitoridae) family is shedding new light on the fishes’ unusual land-walking capabilities, including that of the family’s strangest relative — Cryptotora thamicola — a rare, blind cavefish from Thailand with an uncanny ability to walk on land and climb waterfalls using four limbs that move in salamander-like fashion.
