Thousands of catfish climb waterfalls in first-ever sighting, leaves scientists stunned

Brazilian police witnessed thousands of bumblebee catfish climbing waterfalls up to four meters high on the Aquidauana River in November 2024. Scientists documented how the fish use spread fins, tail movements, and suction mechanisms to scale slippery rocks, likely as part of a spawning migration at the start of rainy season. This first-ever recorded climbing behavior by the rare orange-and-black species provides crucial insights for conservation efforts, highlighting the importance of protecting river systems and migration routes.
