Typical jungle animals, particularly tigers and leopards, occur sparsely in Myanmar.

Smaller mammals are also numerous, ranging from gibbons and monkeys to flying foxes and tapirs. The abundance of birds is notable with over 800 species, including parrots, peafowl, pheasants, crows, herons, and paddybirds. Among reptile species there are crocodiles, geckos, cobras, Burmese pythons, and turtles. Hundreds of species of freshwater fish are wide-ranging, plentiful and are very important food sources.
