With over 750 animals of 170 species, the zoo is world-class, and contains the largest herd of reticulated giraffes in any zoo anywhere. A special feature of the zoo is the fact they allow visitors to hand-feed the giraffes, which are very tame. Hoping to inspire conservation action, the zoo has thoughtfully housed all of its animals in as natural an environment as possible so that visitors can understand the needs of each animal of each species.
