I have no explanation why, but for me the different animals in Africa's savannahs are clearly divided into genders. For example, for me all the wildebeest with their beards and the cool brown-gray tones of the fur are clearly males. It seems like this animal doesn't even exist in a female version! 
It is the same with the graceful Thomson Gazelle - so light-footed and filigree - they can only be females! The African buffalo on the other hand (the article "the" buffalo already says that) is such a lumbering, aggressive powerhouse - there can never be females of this in my imagination! 
The zebra is for me personally the most beautiful variant of the horse, not only by the creative and extravagant design of its fur ... it styles its comb perfectly every morning and without the slightest carelessness from the head to the shoulders ... only women are able to do that!
