One of the most impressive bulls of the Magnificent Seven, Kambaku was identified by his massive and broad head, huge well-matched tusks, hairless tail and the prominent pattern of creases on his trunk. The perfectly round hole in his left ear, possibly caused by a stick, also made him easily recognisable. This great animal became known as the solitary one, as he was only ever seen alone. He seemed to shun the company of young bull elephants or askaris, a normal feature of the social life of old bulls.
Kambaku’s enormous, perfectly symmetrical tusks, evenly matched as to length, weight, thickness and shape, were a distinguishing feature. The left tusk was 8 ft 6 in long, measured 20 in thick at the lip line and weighed 140 lb. The right tusk was 8 ft 8 in long, 20,5 in in circumference at the lip line and weighed 141 lb.
