An unprecedented video appears to climb straight on a waterfall

In the wilderness, catfish lives a long -standing life, evading the disclosure of scientists who hope to learn more about their lifestyles. Thus, when the police received reports of strange groups in the fish of the creep at the bottom of the waterfall, they immediately called a team of scientists to do some of the detectives.

After watching the fish for about 20 hours, the researchers reached the conclusion that these Rhyacoglaanis paranensis-It was a kind of orange and common black fish in South America-very slope waterfalls expand, as a team. A paper published on August 8 in Fish Biology Magazine It records this strange but great moment.

“I would like to say that it was a pleasant surprise for all of us, crazy with fish, to see all the small catfish that gathered in a great effort to climb the rock walls – a great moment!” I told Manuela M. M. Marino, a author and biology at the Federal University of the University of Mato Grosso de Sol, Gismino in an e -mail.

The secret life of the cattle of the fish is clear

The thickness of the creent began to climb after 6 pm, as they gathered in thousands at the bottom of the small waterfalls. The more severe ascending, the more the fish appear to be a superficial anxiety; Some even slide upside down across the cracks. There was more collective action displayed near the rocks overcoming, as the thickness of the snow went up to each other to reach the rock.

The researchers are not completely sure of the reason for fish involved in this behavior. Based on anatomy and the timing of vision, they believe that the fish of the snow was likely to migrate to reproduce. It also does not seem to eat. But this behavior Do It seems that an instinct: “You have also climbed artificial things, such as our plastic lashes,” according to paper reports.

The study shows the value of field notes in environmental science and how Stranging strange reports It can lead to valuable and unexpected discoveries.

I personally thought that the fish of the snow was cold. There is a strangely enchanting thing about their flat sausage structure. Now that we knew that they were good infiltrators? Even cooler.
