German, hippopotamus means Nilpferd. As you can see on the
picture, they feed themselves on vegetations being exclusively
grass and tall plants found along the lakes in which they relax
and decrease their body temperature! Due to their very special
type of skin, which transpires more than others, they must
absolutely go in water. Their skin is also very sensible to the
rays of the sun affecting therefore their whole body. When they
are submerged in the tropical cool water, these hippopotamus
secrete a substance which they use as sunscreen, protecting them
from the sun. This substance becomes firstly red-orange to brown
within minutes. Do not think that they were dipped in mud!
Although these look very much as lazy and heavy animals, they
are said to run faster than us, human beings, on land...
Unfortunately this unbelievable action doesn’t last more than
100 yards long.
