A rare native species, that's restricted to pristine hillstream habitat.
A species that has been facing increased development pressure in the past 2 decades as many of its major habitats in Tung Chung were destroyed or polluted to make way for the Tung Chung New Town. It has now become a rare species due to it's restriction to unpolluted hillstreams.
