Though widely known as a compact urban centre, Hong Kong is rich in biodiversity. Live specimens of our native species such as Romer's tree frog are displayed at the centre for visitors to observe the species closely. Romer's tree frog is endemic to Hong Kong and naturally occurs on Lamma Island, Lantau Island, Chek Lap Kok and Po Toi, etc. It is the tiniest native frog, about 25 millimetres, with an "X" mark on its back. It is a nocturnal animal feeding on small insects.   Close
