The Strange Blind Fish of the Lower Congo River

The Lower Congo River, with its turbulent rapids and deep waters, is home to over 300 unique fish species, many of which are found nowhere else on Earth. The river's powerful rapids create isolated habitats, leading to allopatric speciation. Some fish have evolved extreme adaptations, such as blindness and lack of pigment, due to their isolated environments. The river is a prime location for studying convergent evolution, where unrelated species develop similar traits. Despite its dangers, researchers are working to understand the river's unique biodiversity and evolutionary processes.
