The hippopotamus is a large mammal that primarily lives in water, spending most of its day frolicking in the water to stay cool under the African sun.
Despite their heavy-set appearance on land, hippopotamuses are surprisingly fast in the water and can be very territorial and aggressive. In fact, the hippopotamus is considered to be one of the dangerous land animals in Tanzania and Africa simply because it is so territorial, so don’t be fooled by its otherwise playful appearance.
Nice capture of the group in the water. At Halloween the Sacramento Zoo gives the animals unusual things to stimulate their brains and keep them active. The hippos get pumpkins in their moat. I saw one take the whole pumpkin into its mouth and bite it. After a loud pop, it chewed the whole thing.
