The freshwater rivers lakes and wetlands of tropical India and south-east Asia...
Dragonflies and damselflies are usually the most obvious group of insects around tropical wetlands.
Crocodylus palustris, 'Mugger Crocodile', 'Marsh/Broad-snouted Crocodile'. It is found most commonly in India and Sri Lanka, but is also recorded in Pakistan, Nepal and Iran, but is probably extinct in Bhutan, Bangladesh and Myanmar.
Varanus salvator, 'Asian Water Monitor'.
Bubalus bubalis, '(Domestic) Water Buffalo'. This is the buffalo seen in rice fields all over Asia. There are many wild populations of feral water buffalo through tropical Asia, as well as introductions in Africa and Australasia. (It is presumed to be derived from the wild species Bubalus arnee, which has been reduced to small populations in Asia, mostly in India).
Sus scrofa, 'Wild Boar/Pig'. Widespread throughout Eurasia, tropical Asia, and northern Africa, introduced into the Americas, Australasia and Pacific islands.
Although many areas of south-east and southern Asia continue to be drained for development, there are still magnificent freshwater wetlands to be enjoyed, icluding: Bundala National Park and Talangama Wetlands in Sri Lanka, Paro & Thimpu, in Bhutan and Prek Toal in Cambodia
