A newborn baby pygmy hippo from Rotterdam’s Blijdorp Zoo, is no bigger than a head of lettuce! The pygmy hippo grows to just over 3ft tall - just one fifth of the size of the common hippopotamus and is the only other species of hippo in the world. Reclusive and nocturnal, the mammals are semi-aquatic and need to live near water to keep their skin moisturized and their bodies cool.
