Tanzania Elephant, Tanzania, Africa, 1997

Photo: Tanzania Elephant

African elephants are the largest of the world's land animals. Despite their large stature, they engage in a symbiotic relationship with the small cattle egret. The bird eats insects that are stirred up by the grazing of the elephant.
