Anterior labium has 8 tooth rows of which 7 are medially interrupted. The posterior labium has 3 rows of teeth of which 2 are interrupted. The labial tooth row formula is 8 (7)/3(2). The beak is large, with preoral half strongly arched and finely serrated, overhanging similar postoral half (Khan and Malik 1987a). Total length of the tadpole 75 mm, tail 65 mm. Distribution and Habitat Country distribution from AmphibiaWeb's database: India, Pakistan
Life History, Abundance, Activity, and Special Behaviors The tadpole is a typical Himalayan torrenticole habits (fast-moving aquatic habitats). It feeds on algal growths on the surface of submerged stones. Tadpoles of Euphlyctis cyanophlyctis also occur in these pools. During rainy season, to avoid the fast flow of water, the tadpoles either migrate into crevices under stones where the force of flow is minimum, or hold on to the surface of rocks with the oral disc which acts as an effective sucker giving the tadpoles a very firm hold.
