Elephants

In this photograph, a baby elephant is seen hugging its mother very lovingly. The elephant may not have the intelligence of a human but, it sure has the heart and the emotions.
The elephants have a matriarchal society. The female elephant has a gestation period of 18-22 months and a calf suckles its mother for about 3 years. If a mature calf is female it stays with the herd and if it is a male it is chased away.
The elephant featured here is the Asian elephant whose population is about 60,000, which is 1/10th of its African counterpart. About 13,000 of these are domesticated and in zoo's.
Elephants communicate with low frequency sounds, way below human hearing capacity.
