Deaths of elephants

African elephants are the world's largest terrestrial mammals: Adult males can weigh more than 6,000 kilograms, females average about half as much, and newborns about 100 kg. They are sociable, intelligent, proverbially capacious in memory, and eerily aware of death, as they show in their remarkable behavior when they encounter the bones of their ancestors. Although their bones have remained in Africa, their tusks have often ended up in piano keys or in the ivory bric-a-brac you still see sometimes on mantelpieces.
