While all African
elephants grow tusks, only males among Asian elephants carry ivory. Among these, it is just about 6-7% of all male elephants in Sri Lanka who are blessed with this precious commodity.
Tusks are, in fact teeth (incisors), and are
classified as ivory
Molars (grinding teeth) are 1 foot long (30 cm) and weigh about 8 lbs.
(4 kg). The animal has only four of these teeth at any one time. An elephant usually grows six sets of these molars in a life-time. The final set grows when it is about 40 years of age. The last set decays when it's around 60 – 70 years
An elephant's tusks never stop growing
The massive ears act as radiators with millions of blood vessels through which passing blood is cooled instantly.
