Scientists in Thailand have discovered a new fish species that is pink, blind, and can “walk like a human> because it has a pelvis. That is right, this fish, called the waterfall climbing cavefish (Cryptotora thamicola) can not only walk, but it can climb up the rocks of waterfalls while completely underwater. According to the scientists, the fish uses its pelvic and anal fins to climb up rocks as water comes down them, according to CBC News.
“They have fin structures unlike any fish that I have ever seen anywhere,” said Brooke Flamming, a biologist at the New Jersey Institute of Technology who governed the experiment, in a press release.
Flamming says that the cavefish moves in the same way as four-legged land creatures and climbs up rocks just like a salamander does, but lacks fingers or digits in each of its limbs. The researchers also say that the pelvis and vertebral column of the fish holds its body weight against gravity, enabling their muscles to freely walk. The researchers published their findings in the journal Scientific Reports.
