What's black and white and red all over? A zebra with a sunburn! Everyone knows that old riddle, but what else do you know about zebras? The Grevy's zebra is the largest of the three zebra species. It can weigh almost 1,000 pounds. And it has the skinniest stripes or any zebra, which run all the way down to a white belly and rump—other zebra species have stripes on their belly. The Grevy’s zebra’s legs are lined with fine striping all the way down to the hooves. It also has large, rounded ears. Some zebras like to live in little groups. But for Grevy's zebras, it's "the more the merrier!" Their family groups can number up to 20. Did you know? Zebras are attracted to black and white stripes. If stripes are painted on a wall, a zebra tends to stand next to it.
