The elephant is the largest animal to walk on Earth. An elephant can carry a load of 1,200
pounds (磅). They eat 300 pounds of food a day. An elephant baby can weigh 200 pounds at birth.
Elephants can live up to 70 years.
Elephants can be trained to carry logs with their trunks (象鼻), and have been used in the forestry
industry in Asia for many years.
Elephants use their ears as a cooling system. Blood flows through veins (静脉) in the ears and as
the elephant flaps (拍击) his ears, the blood cools and flows through his body to cool off other parts.
There are two kinds of elephants: the African elephant and the Indian elephant. African elephants
can be identified (识别) by the larger ears. The African elephant grows up to 10 feet tall and weighs as
much as 12,000 pounds.
The Indian elephant grows up to 9 feet tall, and weighs up to 8,000 pounds. It's easy to identify
because of its smaller ears. Most circus (马戏团) elephants are Indian elephants. Another name for
the Indian elephant is the Asian elephant.
