African elephants are one of the most endangered species in Africa. They have been hunted for their tusk during and prior to colonization. Before colonization ivory tusk were often traded for slaves. These animals are as ancient as the dinosaurs and they remain the strongest land animals on earth. Elephants are also considered to be one of the most intelligent animals on earth. As strong as they are their tender hearts are most admirable. Elephants live in families that the entire head raise and protect their young. Elephants also mourn and bury their dead in special elephant graves.
