Distribution and Habitat
Country distribution from AmphibiaWeb's database: Bangladesh, India, Nepal, Pakistan, Sri Lanka
Abdulali (1962) reported large numbers of this frog in Khanapur, Mysore, southern India, in the month of May. This species is widely distributed in southern and eastern India, extending into northern Sri Lanka (Kirtisinghe 1957). Common in southern India.
Life History, Abundance, Activity, and Special Behaviors
While it is burrowing. the loosened soil is thrown sideways by its powerful hind legs and the animal sinks into the cavity so formed, with the eyes the last to disappear underground. Moist soil is essential for this frog. During dry months the frog retreats into the moist environs of termite nests, termites being its main food item (Mukerji 1931).
Mukerji (1931) collected a specimen of this species from a depth of 1-1.5 m. It had lived for 13 months without food. The body of the frog is globular due to the enormously developed inflated lungs.
The breeding season extends from May to July, during monsoon rains (Ferguson 1904). The males call from the banks of torrents or paddy fields. The call is like a bleating goat, and during calling the subgular vocal sac is distended so enormously it looks like a float. The eggs are laid in masses which float on the surface of the water (Ferguson 1904; Annandale and Rao 1918).
