(Kaloula pulchra)
The banded bullfrog (Kaloula pulchra) is a species of frog in the narrow-mouthed frog family Microhylidae. Native to Southeast Asia, it is also known as the Asian painted frog, digging frog, Malaysian bullfrog, common Asian frog, and painted balloon frog. In the pet trade, it is sometimes called the chubby frog. Adults measure 5.4 to 7.5 cm (2.1 to 3.0 in) and have a dark brown back, with stripes that vary from copper-brown to salmon pink. The banded bullfrog lives at low altitude and is found in both urban and rural settings, as well as in forest habitats. They bury themselves underground during dry periods and emerge after heavy rainfall to emit calls and breed. They feed primarily on ants and termites; predators of adults and tadpoles include snakes, dragonfly larvae, and snails. When threatened, they inflate their lungs and secrete a noxious white substance. The species is prevalent in the pet trade and is a potential invasive species. The banded bullfrog is medium-sized with a stocky, triangular body and a short snout. Males grow to a snout–vent length (SVL) of 5.4 to 7.0 cm (2.1 to 2.8 in) and females are slightly larger, reaching an SVL of 5.7 to 7.5 cm (2.2 to 3.0 in). Other than the slight difference in length, there is very limited sexual dimorphism. They have a body weight of 80–120 g. The back is dark brown with stripes that vary from copper-brown to salmon pink, and the abdomen is cream-colored. Tadpoles are about 0.5 cm (0.20 in) long after hatching and reach an SVL of about 1.1 cm (0.43 in) at the end of metamorphosis. They have an oval body that is brown or black with a pale belly, a round snout, and a moderately long, tapered tail with yellow speckles and tall fins. The eyes are relatively small and the side of the head, with black or dark gray irises and a golden ring around the pupil. They do not possess any tail filament. During metamorphosis, their eyes increase in size and bulge and they develop slender limbs and digits with rounded tips. The tadpoles metamorphose beginning at two weeks. The species is native to Southeast Asia. It is common over a range from northeastern India, and Nepal, to southern India and Sri Lanka to southern China (especially Hainan) and Myanmar, and south to the islands of maritime Southeast Asia. Its wide distribution, compared to the related species Kaloula assamensis, has been attributed to its burrowing ability.
