Vundu

The vundu (Heterobranchus longifilis) is a species of large airbreathing catfish found widely in rivers and other freshwater habitats of sub-Saharan Africa, as well as the Nile. It is also called the sampa, cur, lenda, or certa.

==Description== The vundu is the largest true freshwater fish in southern Africa, reaching up to in length and in weight. (Bull sharks are also found in southern Africa and reach a larger size, but occur in both fresh and saltwater.) Few other catfish have such large second dorsal fins (adipose fins) or such long barbels as do the vundu. Its barbels nearly reach to the origin of the pelvic fin. The colour of Heterobranchus longifilis is light to dark olive brown on its dorsal surface, getting lighter over the mid-body to a light brown. Its belly is off-white. Fins are usually light brown.
