Never joke with hippos; they are always unpredictable and ready to defend their territory. Hippos may appear gentle and friendly, yet it's the most dangerous mammal in africa, killing more people every year than lions, leopards, and crocodiles combined. #hippo #hippos #hippopotamus #riverhorse #boatsafari #wildlife #gamedrivesafari #boatcruise | Wildfriends Africa

Ever wondered how hippos keep their eyes safe underwater? Take a closer look at Kasai! Those 'built-in goggles' you see that make her eyeballs look so thick, are actually clear membranes shielding her eyes. Those membranes protect her eyes while she has them open underwater. Hippo eyes also have one of the greatest degrees of retraction among animals and very strong eyelids. #KeeperCam | Cheyenne Mountain Zoo
