An Elephant Calf Often Sucks Its Trunk for Comfort.

Elephants are very social animals, they communicate using a variety of low frequency grumbles and rumbles which can be picked up 6 miles away. They live in family groups of up to 100 members, headed by a matriarch. Elephants are social and affectionate animals. Elephant mothers are very attentive to their babies, orphans are nursed by other mothers in the group. A young elephant is weaned at 4-5 years old, when their tusks start to get in the way, and they may move out of the family group at 10-12 years old. Elephants prefer one tusk over the other, just as people are either left or right-handed. Elephants waive their trunks up in the air and from side to side to smell better.
