Description: The African sharptooth catfish, is a large freshwater species notable for its elongated body and distinctively long dorsal and anal fins, which aid in its streamlined swimming. Its skin is smooth, with a dark gray to brown coloration, sometimes featuring lighter underbellies. This catfish can grow impressively large, often reaching over 1 meter in length. Found predominantly in African rivers and freshwater lakes, it adapts well to low-oxygen environments, thanks to an accessory breathing organ, making it highly resilient in diverse habitats.
