Weird Walking Fish Is A Living Link To A Key Moment In Evolution

It may not seem like much — a little blind cavefish writhing its road up a rock-and-roll — but investigates say this is one of the most unique fish on the planet.

“What these fish do in complete darkness is they stick to the rock and they climb cataracts altogether underwater, ” Daphne Soares, an associate professor at the New Jersey Institute of Technology, said in a video news release.

The fish, may be in Thailand, is called Cryptotora thamicola, and the direction it can walk and climb is unlike any other known fish. In happening, it moves nearly like a salamander, Soares and her fellow investigates wrote in the journal Nature Scientific Reports.

They believe this fish may be a living link to a key instant in growth, when finned mortals of the sea became the limbed individuals of the estate.

While there are other fish that they are able appear to walk, they use their fins and generally will vary depending on the flow of water around them to keep upright.

But, according to the brand-new experiment, this cavefish is able to support its own bodyweight against gravity expending its pelvis and vertebral column.

A 2009 video shows the fish in action:

“From an evolutionary position, this is a huge determine, ” answered Brooke E. Flammang, also an assistant professor and the other another author of the working paper. “This is one of the first fish that we have that is a living species that acts in a way that we think they must have acted when they advanced from a liquor home to a terrestrial environment.”

She said the fish could offer a peek at the moment in evolution when life transitioned from the sea to the land some 420 million years ago.
