Changes

Apart from their massive size, their most striking features are a long trunk, or proboscis, and a flexible nose strong enough to lift heavy objects. Their skin is up to 1.5 inches thick and gray, with African bush elephants more heavily wrinkled than their Asian counterparts. All three species have ivory tusks, but female Asian elephants generally lack them unless they are rudimentary in size, and even then they are usually only seen when the mouth is open. The legs are columnar and massive; the feet are broad and round.

The African species differs from Asian elephants in the overall shape of the back; it is "saddle-shaped," i.e., the back is concave in the center, while the Asian species has a distinctive hump or arch. African elephants also have larger, fan-shaped ears that extend over and nearly completely cover the neck; Asian elephant ears are much smaller. African elephants have two finger-like processes at the tip of the trunk, while Asian elephants have one. Both species have five toes on the forefeet, but the African elephant has three toes on the hind feet; the Asian species has four, and sometimes five, toes on the hind feet.
