The term 'Safari Beast' refers to two animals that can be found on safaris in Africa: the rhinoceros (5 letters) and the wildebeest, also known as the GNU (3 letters). The rhinoceros is a large mammal with thick skin and one or two horns on its snout. It is an herbivore and is considered to be a vulnerable species due to poaching and habitat loss. The wildebeest, or GNU, is a large antelope with a long face and curved horns. It is a grazer and is considered to be a common species.
