Indus Valley Bullfrog, Hoplobatrachus tigerinus

The Indus Valley Bullfrog (Hoplobatrachus tigerinus) known also as the Indian Bullfrog, Asian Bullfrog, Asean Bullfrog, or the Asia Bullfrog, is a large species of frog located in Myanmar, India, Bangladesh, Pakistan, Afghanistan, and Nepal.

The vomerine teeth are in two strong and oblique series originating from the inner anterior angle of the choanae. The lower jaw does not have very prominent bony processes in the front. The head is of moderate size and the snout is more or less pointed. The nostril is a little closer to the end of the mouth than to the eye. The interorbital space is narrower than the upper eyelid and the tympanum is distinct and about two thirds of the size of the eye. The fingers are rather short with the first one stretching beyond the second. The toes are moderate, almost entirely webbed and obtuse. A much developed membranaceous fringe is along the fifth toe. The skin of the back has longitudinal folds. This frog is green or olive colored above with dark spots and frequently a light vertebral line. The male individual has two subgular vocal sacs which are conspicuous externally by the folds of the skin on the sides of the throat.

It is fundamentally aquatic, and is said to jump over the water surface much in the same way as on land when they are frightened.

From the snout to the vent the bullfrog measures about 6.5 inches.

On the IUCN Red List, it is classified as Least Concern.
