Hippos: “You like see food?” Jaws for crunching, teeth for munching, and lips for suction? Hippos spend most of their day foraging and use their strong lips to grip and pull vegetation out of the ground. The suctioning sound you hear when Ama and Food are eating off the ground is their lips trying to grasp the food. #Hippo #Snack #Noms #Yum #SanDiegoZoo
