• Rana tigrina refers specifically to the Indian bullfrog or Asian Bullfrog due to their population distribution in areas such as Bangladesh, India, Myanmar, Nepal, etc.

• The trunk is provided with a pair of fore and hind limbs. The fore limbs are shorter and stouter, end in four digits.

• The hind limbs are much larger and muscular than the fore limbs, end in five digits. The male and female frogs can be differentiated externally.

• The dorsal surface of frog is spotted olive green and ventral pale yellow; this protective colouration help to camouflage i.e. escape the detection by enemies.
