Chiang Mai Night Safari welcomes its new member, a pygmy hippotamus born of 'Bomb' and 'Bay', both 14 years old, bringing the total number of pygmy hippos at the zoo to four. A pygmy hippo is a tenth of a regular hippo in size, at one metre high, 75-100cm long and weighing 180-275kg. A rare nocturnal forest creature, it is herbivorous, feeding on ferns, broad-leaved plants, grasses and fruits.
