This was the result of a research project on amphibian-reptile biodiversity developments in the Can Gio Mangrove Biosphere Reserve carried out between September 2006 and March 2008, said the project’s director Nguyen Ngoc Sang.

The species include water toad, green bullfrog, grey salamander and several species of snakes.

The research also showed that several species, including large-belt snake, lilac-coloured crocodile, no longer live in the area.
