I understand you defend leopards, but do you really want another giraffe, zebra or lion to spiol one of the Afrikans 8 precious spaces? Those Masai Giraffe or Grevy Zebra don’t behave any different at all.
I agree with not preferring simple reskinned animals, such as a Massai giraffe.
However, I would like to point out that Grevyi zebras actually do behave very differently from plains zebras
They are wandering animals and live solitarily, except mothers with their foals. Males guard their territory fiercely and mate with females who are passing through. This is very unlike plains zebras, who live in herds that consist of a male and his harem. Males guard their harem, not a territory.
And then of course there's the physical differences, which are striking! Grevyi zebras are much larger than plains zebras. They have very large ears, almost like a donkey, and their noses are brown instead of black. Their stripes are very thin instead of thick and wide like plains zebras, and their belly is white because the stripes don't go underneath like with the plains.
Fun facts: Grevyis and plains zebras come across each other in the wild, and because Grevyi zebras are so large and aggressive they easily displace plains zebra males from their herds. However, Grevyi males aren't interested in taking care of a herd so they quickly move on. The resulting crossbred offspring have a phenotype in the middle between both species.
Here you can see just how much larger a grevyi zebra is compared to a plains zebra:
Below is a grevyi x plains zebra hybrid:
And here is a hybrid male fighting with a pure plains male. You can see how the hybrid is still much larger than the pure plains. The stripes are thinner, some go over the belly and others do not, and the rear pattern is an intermediate between the grevy and plains patterns.
