Family Equidae Genus Equs so the same family and genus as the horse and tthe donkey.
The burchells and Hartman’s are supposedly more horse like and the grevys more ass like.
Hopefully someone much wiser than me will chip in.
This is correct. The Grevys is an ass. They are also much bigger than a Burchells. Once you see a Grevys in real life you’ll forever call the other zebras “ponies” because they will look awfully small in comparison. Male Grevys can almost hit 1000 lbs, whereas a Burchells will be 500-550 or so. They are remarkable to see in the wild partly because of where you see them. I saw them in the NFD of Kenya.
