Ruben takes care of square-lipped rhinos

Square-lipped rhinos capture the imagination of many visitors: the colossal, somewhat prehistoric-looking mammals inspire admiration and awe. While impressive to behold, rhinos are less dangerous than many people think. “Square-lipped rhinos are actually extremely quiet, peaceful animals,” explains head keeper Ruben. An adult square-lipped rhinoceros bull can weigh up to 3,000 kilos, while cows usually reach around 2,000 kilos. Despite their demure nature, their incredible weight and great pushing force mean you want to avoid unintentionally ending up between a rhino and the wall. “As zookeepers, we are careful never to underestimate the incredible power of these large mammals, and we always work hands-off with the rhinos. That includes never being in the enclosure at the same time as the animals. But rhinos certainly do not have an aggressive, hot-tempered nature—they are gentle giants.
