We examined the prey selection and behavioral responses of tiger frog
Hoplobatrachus chinensis
larvae exposed to unpalatable and palatable sympatric prey tadpoles,
Bufo melanostictus
and
Pelophylax nigromaculatus
. We found that after a short exposure to the toxic toad tadpoles
B. melanostictus, predators may learn to decrease going after unpalatable prey, subsequently it seems they may express short-term behavioral memory in order to avoid the toxic prey. In general,
H. chinensis showed no preference for either any of the two prey species, which may be the result of
P. nigromaculatus using behavioral performance and chemical defense as antipredatation strategies. These results facilitate further investigation of other aspects of the behavioral ecology of these three anuran species and hint at some potentially interesting possibilities of memory in choice of prey which may suggest
further study.
