Medium Summary
Bumblebee catfish, a small and rarely observed species native to Brazilian rivers, were filmed climbing a waterfall as high as 13.1 feet. The fish exhibited unique climbing behaviors, including tail-flipping and possibly suction mechanisms to stick to rocks. Researchers believe this mass migration is linked to reproduction, triggered by environmental changes following a severe drought. This discovery highlights the importance of preserving river habitats for small fish species threatened by damming projects.
