Why are tadpoles on the lotus leaf?

Tadpoles are found in spring, usually in March-April; Lotus leaves grow in late spring and early summer (May-June), with the most flourishing growth in summer. The newly hatched tadpoles are spindle-shaped, with no limbs, mouth and inner gills, long tail, flat side and branched outer gills on both sides of the head, which are adsorbed on aquatic plants and fed by the remaining yolk in the body.
