Did you know Zebras can snooze standing up? Like other hoofed animals, such as horses and giraffes, zebras have locking joints. This means they can subconsciously lock their knees into position and doze without worrying about falling over. This ensures the zebras are alert to predators and can escape quickly if they feel threatened. #zebras #lakenaivasha #zebrasofinstagram #wildlifephotography #sceniclocations #uniquelocations #uniquedestinations #africansafari #ibetyoudidntknow #didyouknow #wil

Odd-toed ungulates walk on one or three hooves, while even-toed walk on two or four hooves. On this International Ungulate Awareness Day, we celebrate our many ungulate species! | San Francisco Zoo | Facebook
