Baby hippo walking towards the water with its mother

Baby hippos are among the largest baby
mammals in the world.
Since hippos are the third-largest land
mammal, behind only elephants and rhinos, you can probably imagine that they have massive babies. In fact, the average baby hippo is born weighing around 100 pounds!
Hippo calves will eventually grow to weigh
3,000 pounds or more as fully-grown adults.
They primarily depend on their mother's milk, which is rich in nutrients and fat, to help them gain weight. Since hippos spend
much of their time in water, calves must nurse underwater. They close their eyes and
nose when feeding to avoid sucking in water
while they eat.
