An uncommon species which inhabits large rivers (Ref. 4967). Largest freshwater species in southern Africa; occurs in large deep rivers within the mainstream or in deep pools and lakes or backwaters (Ref. 7248, 78218). Most active at night, feeding on any available food, including invertebrates and insects when small, fish and other small vertebrates when large; scavenges off large carcasses and offal from riverside villages; live for 12 or more years (Ref. 7248).
