A blind cavefish named Cryptotora Thamicola can climb waterfalls, says a study published in Scientific Reports on March 23, 2016. These fish use a unique method of movement due to which it can walk like a 4-legged animal.
Co-author of the study, Brooke E. Flammang from Jersey Institute of Technology stated that it possess morphological features that were earlier found only in tetrapods, amphibians or 4 footed mammals. The vertebral column and pelvis of this fish help it support body weight and offer large sites for muscle attachment to walk.
When Flammang first saw this pink fish in footage taken by Daphne Soares, the co-author, she was shocked by the salamander-esque wiggle. Although other fishes use fins in feetlike ways, Cryptotora Thamicola has taken this skill to new heights.
Flammang stated that this was ridiculous and never expected fish to do that. Even though it is put into complete darkness into caves, it sticks to the rock behind the waterfall and climbs its way to the top. It is very unusual as researchers don’t expect a blind fish to function this way.
Scientists are of the opinion that even ancestors of land animals moved in similar ways when they were first dragged out of the sea.
Flammang stated that this is a great finding if they talk about an evolutionary perspective. This is the 1st fish that as a living species acts in a similar way as it must have acted when it evolved to a terrestrial environment from a fluid environment.
So what are your opinions? Aren’t you startled by the fact how this blind fish can climb waterfalls?
