There are two main types of buffalos, the water buffalo and the cape buffalo. Buffalos can be dangerous especially when they're provoked. Water buffalos mainly live in water however they do come out to land sometimes. Water buffalos have been known to cause a lot of damage especially to ships and small boats which with their big sizes they can overturn easily. The Big Five also includes the leopard.
Leopards spend a lot of their time on trees and are forest animals.
Unlike the lion, leopards don't like the savannah and therefore they prefer forest environments. Many people mix up the leopard with the cheetah as they look alike, however a careful observation will show that their spots are shaped differently. Cheetahs eat mainly wildebeest and once they're done their remainders make good food for vultures.
