Spotted-Necked Otter in the Lower Orange River, Northern Cape, South Africa

An out-of-range sighting of a spotted-necked otter, Lutra maculicollis, was recorded on the lower Orange River at Senderling's drift (28°7′S; 16°53′E), in the Ais/Ais Richtersveld Transfrontier Park. Notes are provided on its observed behaviour, which corresponds with that of its known biology. This record is 1200 km downstream from the known distribution. Mammal species inventories need to be more meticulously undertaken so as not to overlook any species, and particularly larger mammals.
