A hippo at the National Zoological Park in New Delhi, India went right up to the edge of its enclosure to investigate some visitors in this nerve-wracking clip. <br /><br />The hippo was kept in an enclosure circled only with a low fence, and walked up to within touching distance of the visitors on November 11, but remained calm while watching them. <br /><br />The visitors took photos and can be heard praising the dangerous animal for how calm it was being, before it eventually returned back to its lake. <br /><br />The filmer commented: "Such a great bonding between animals and visitors inside zoo."
