Abstract
The schooling behavior of Hyla semilineata Spix, 1824 tadpoles is described. Experiments were carried out both in the natural environment and under controlled conditions to quantify the constant movement of these tadpoles. Bullfrog tadpoles (Rana catesbeiana Shaw, 1802), similar in size to the H. semilineata larvae, were used as controls in the experiments. Hyla semilineata tadpoles remained stationary for one sixth of the time that the bullfrog tadpoles did and the number of individuals of H. semilineata moving at any given moment was about seven times greater. The schooling behavior and constant swimming behavior of these tadpoles may enhance the effect of their warning coloration.
