here is an example of two elephants of similar size, I believe, but vastly different sized tusks. They were part of a larger group of mixed ages.
I was amazed how the tusks on the elephant on the left of the photo differ, one curved, the other straight
I had read about how elephants were right or left tusked, they would favor one side over the other, similar to our being right or left handed.
"What is a tusk?
Usually in mammals tusks are enlarged canine teeth, but in elephants they are actually elongated incisors and are essentially no different from other teeth. One third of the tusk is actually hidden from view, embedded deep in the elephant’s head. This part of the tusk is a pulp cavity made up of tissue, blood and nerves. The visible, ivory part of the tusk is made of dentine with an outer layer of enamel. . . .. Evidence suggests that elephants normally prefer one tusk over the other, similar to being left or right handed in humans. The preferred tusk is known as the master tusk." -

we saw elephants feeding. of course, but never were lucky enough to see any of them use their tusks in their search for food or water.
