The term "Big Five" is reminiscent of the old safari hunting days. The members of the Big Five were chosen for the difficulty in hunting them and the degree of danger involved, rather than their size.
The animals behind the The "Big Five"' are Lions, Leopards, Elephants, Buffalo's and Rhinos.
Countries where all the members of the big five can be found include Botswana, Zambia, Uganda, Namibia, Ethiopia, South Africa, Kenya, Tanzania, Zimbabwe, the Democratic Republic of the Congo, and Malawi.
