National Geographic’s Nature Photographer of the Year 2016 contest
A hippo charges in Botswana’s Chobe River in April 2016. This very territorial bull made a charge whenever a boat (driven by a local guide) passed his patch of the river. See Kurtul’s profile. Sam Kurtul/2016 National Geographic Nature Photographer of the Year
