For the first time, scientists have filmed a species of tiny African fish, the shellear Parakneria thysi, successfully climbing a 50-foot waterfall in the Luvilombo Falls of the Congo Basin. These remarkable fish have long been the subject of rumors, and recent observations confirm their ability to scale vertical cliffs using hooked fins. The arduous climb takes approximately 10 hours, showcasing an extraordinary adaptation to their environment. This discovery has shed light on the incredible capabilities of these fish, previously only hinted at in anecdotal reports.
