Isilo (c. 1956 – 2014) was one of South Africa’s largest African elephants and the largest living tusker in the southern hemisphere before his death. He was known as a tusker, a male elephant with tusks weighing over 100 pounds. Although Isilo died of natural causes relating to old age, his death attracted international media attention because his tusks, considered a National Heritage artifact, were missing when his body was discovered.
