Box jellyfish
In Australia (mainly northern; however, box jellyfish can live in subtropical waters as far south as Sydney, with "Carybdea marsupialis" being recorded as far south as Bermagui, Sapphire Coast) the highest risk period for the box jellyfish is between October and May, but stings and specimens have been reported all months of the year. Similarly, the highest risk conditions are those with calm water and a light, onshore breeze; however, stings and specimens have been reported in all conditions.
Wang Thong River
Kaeng Bang Rachan at the source of the Wang Thong is a natural habitat for the freshwater jellyfish ("Craspedacusta sowerbii") which is presently found in only the United States, Russia, the United Kingdom, Japan and Thailand.
Also, it is a natural habitat for rare species of butterflies such as kaiser, "Troides helena" and "Euploea".
