where they are found in holes in tree-trunks, infested with ants, about one and a half meters above the ground. They descend from these tree holes and hollow trunks climbing down backwards. When dug up, they inhale air and swell up like a ball, keeping the head down and secreting a white slimy fluid through pores in the skin. They hop slowly but swim well. The call is distinctive and seems like the grating of a coconut. Reported earlier from West Bengal ( Sarkar, Biswas and Ray, 1992 ) and Deuti (1995).
