Hippopotamus

The hippopotamus is the third-largest mammal that resides on land next to the white rhino and the elephant. Their feet are webbed to evenly distribute their weight both on land and it the water. Their tail is flat and works as a paddle to spread excrement to indicate their status and mark their territory.

The hippopotamus is approximately 13 feet long and five feet tall, weighing up to 3-1/2 tons.  Their lifespan is 50 years. They reside mostly in rivers and swamps. The female has a gestation period of 240 days and usually gives birth in the water, while teaching the baby to swim early on. A newborn weighs about 55 to 120 pounds and is highly protected by mom from predators such as crocodiles, lions and male hippos.

There are two types of hippos, the larger hippopotamus that lives in East Africa and its much smaller variety that weighs between 440 and 600 pounds. Their main diet consists of green grass and other vegetation.
