Photo of species-rich assemblage of fishes in the lower Congo River.

The lower Congo River is home to a species-rich assemblage of fishes. Many are known only from the region (endemics), and many display bizzare anatomical features such as elongation, pigment loss and reduction or absence of eyes. This image shows a small selection of species found.

One of the large predators of the river, a Tiger fish (this one is Hydrocynus vittatus), shares the river with its relative, the Giant Tiger fish (Hydrocynus goliath). The Tiger fish can reach up to a meter in length, while the goliath can reach nearly a meter and a half and weigh nearly twice as much.
