Big 5 - The Lion

(Panthera leo) Most people will hope to see a lion or three while on safari in Africa. Luckily they are not quite as difficult to spot as the rhino or leopard. You have a good chance of seeing lion at most of the major game parks in southern and eastern Africa. Unlike most felines, lions are actually quite social and live in prides of up to 15 members. So, you can get the chance to watch the little ones play and interact with their bored looking mothers. There is nothing quite so chilling as hearing a lion roar in the night while you are camping but they are actually not prone to attacking humans unless you're unlucky and come across a man-eating lion.

Big 5 - The Leopard

(Panthera pardus) While leopards are more numerous than rhino in the Big 5 pantheon, they are sometimes just as difficult to spot while on safari in Africa. Leopards use trees as observation platforms and for protection, so you have to remember to look up to see this solitary, beautiful cat. Leopards are shy and nocturnal, quite modest for a cat that can climb, swim and live in a wider range of habitats than most other wild cats.

Big 5 - The African Elephant

There are two distinct species of African elephant: African Forest Elephant (Loxodonta cyclotis) and the African Bush Elephant (Loxodonta africana).
The largest mammal in the world is remarkably adaptable; you can see elephants in rain forests, deserts and savannahs while on safari in Africa. Elephants are usually quite peaceful if left alone, but if they feel threatened, watch out. There's nothing quite like being charged at by 12,000 lb's of animal, flapping its ears and trumpeting loudly.
Did you know that an elephant's trunk has more than 40,000 muscles?

Big 5 - The Cape Buffalo

(Syncerus caffer) When you spot the Cape Buffalo while on safari in Africa, you usually don't spot them alone. They tend to appear in very large (and intimidating) herds. Even when looking at them through binoculars from a distance, the males always seem to be staring right at you with intense dislike. Weighing in at over 700 kg's (1540 lb's) even lions don't dare take a chunk out of this beast. Cape Buffalo are said to have killed more big game hunters than any other animal in Africa. Hence they have earned their place in the Big 5.

Big 5 - The African Rhino

In Africa, there are two distinct species of rhinoceros; the Black Rhinoceros (Diceros bicornis) and the White Rhinoceros (Ceratotherium simum). Both of these species have two upright horns on the snout.
Rhinos are large mammals (only second in size to the elephant), shortsighted, bad tempered but magnificent to look at. Unfortunately there aren't too many to look at these days due to poaching. Rhino horn, used for medicinal purposes, is much prized in the Middle East and the Far East where it is more valuable than gold.
There are two species of rhino in Africa, the Black rhino and the White rhino, both of which you can see while on safari. Black rhinos have suffered the most drastic reduction in population in the last 20 years.
