There are two different types of elephants, Asian and African. Up until my visit to Have Trunk Will Travel, I could never tell the difference. But Kari Johnson gave me a fool-proof method. Now I can’t believe I couldn’t distinguish between the two in the past.
Asian elephants have a humped back whereas African elephants have a sway back. You probably also notice from the photos that Asian elephants have shorter trunks, wider legs, and their leg does not taper much above the foot. Asian elephants have a bilobed forehead whereas Africans have domed head.
