This liquid is not sweat. It so happens that hippo’s skin becomes dry as soon as it comes out of water. Further, its skin is comparatively thin and soft, but has large pores on it. In dry air hippo’s body loses water at a faster rate which is four times greater then that of a human being. So to prevent its dry skin from cracking Nature has provided hippo with a gland that secretes a cold cream-like thick sticky liquid. After filing up pores that pink liquid becomes somewhat dense and closes the poses to prevent water loss. Hippo is the only animal which in spite of being ugly cannot do without its cosmetic ‘cold cream’.
