Ecological Correlates The adult Microhyla ornata is sharply contrasted from its sympatric ranoids in its choice of breeding site and mode of egg deposition. Usually its breeding sites are deep ponds, which develop rich planktonic bloom during summer. Such sites are quite restricted and rare in temperate Punjab, unlike sympatric ranoids who breed in temporal sites that dry in the summer. Inter- mittent unpredictable rains or irrigation seepage saves such populations of tadpoles (Khan and Malik, 1987b). Table 1 and 2 summarize peculiar features of M. ornata tadpole necessary to suit its lentic habits: per- fectly streamlined transparent body and long broad finned tail with independently vibratile terminal fla- gellum, lateral eyes, median ventral spiracle, abdomi- nal silver-shine, are adaptations to nektic habits of the M. ornata tadpole. A school of tadpoles swimming at midstream is almost invisible from above the water due to tadpole's transparent bodies. Meanwhile abdominal coloration makes them invisible in water since the water surface viewed from inside appears shiny due to reflection of light from water. A vibrating tail flagellum and the jet of water from median ventral spiracle supports the microhylid tadpole at mid- stream, while its buoyancy is maintained by dorsally placed air filled lungs. A long broad finned tail helps the tadpole to react quickly to any stimulus including enemies and food in the water column above and below. Microphagous tadpoles are characterized by an exaggerated oropharyngeal region (Wassersug, 1980). All oropharyngeal modifi
