Dance of the nighttime hippos 🩰 Nighttime Zoo is happening now, and it's a tutu-riffic chance to experience the Zoo after hours and see nocturnal wildlife, like hippos, when they're at their most active. You may just get to witness these twirly girlies spar, splash, and pirouette across their underwater world, natural ways the hippo gals socialize and engage with one another. #hippo #sandiegozoo #nighttimezoo
